Enemies of science

Science always seems to be under attack. Basic scientific teaching has been under attack by creationists since evolution was first discovered. The only thing that has changed with time is that even more science is under attack from various directions.

Social, behavioral and economic (SBE) science research is the latest target by conservative Republicans. It seems like they are beginning to make have an effect on the budgets, and therefore the research, of the various sciences.

Roll Call reports on the cuts led by people like Tom Coburn (R-OK). They even include a plausible reason why they are making those cuts:
Despite such obvious benefits, critics of SBE (social, behavioral, and economic) programs have asserted that they provide few societal returns and are rife with examples of frivolous research. But there might be a more insidious reason for such opposition: a conviction that SBE research outcomes will not conform to conservative ideology.
The longer our nation operates by trying to ignore basic scientific research in order to meet nearsighted conservative goals, the more danger our nation is in of falling behind the rest of the world and seeing our economy reliant on other countries' prosperity. If that happens, we won't have anyone to blame but the rest of the idiot Americans.

Inhofe's Christian Crime Connection

While Sen Jim Inhofe (R-OK) might not have a formal Christian crime ring, his actions would make more sense if he did. I can almost imagine him saying something like, "Nice planet you got there. It'd be a shame if something happened to it."

I generally believe that there isn't anything inherently wrong with being a Christian. While I feel confident that Christians are wrong in their beliefs, I also don't feel like those beliefs steer them in a heinous direction. People can generally be good with or without god. It has to do more with someone's moral grounding which is mostly shared by the religious and non-religious. But Jim Inhofe gives a perfect example of why there is still a danger to the world from Christianity.

In a response to The News on 6 in Oklahoma, Inhofe said:
"The book of Genesis tells us that the cold and heat, summers and winters will not cease, and I believe the God who spoke these words is still up there and in control. We have seen environmentalists disregarded the term 'global warming' and adopt the phrase 'climate change,' because there will be cold, there will be heat, there will be summer and there will be winter, but the earth shall not cease. Furthermore, more than 60 percent of weathercasters recently polled for a study done by George Mason University believe that any global warming that occurs is the result of 'natural variation' and not 'human activities.' There is no question that we should be good stewards of what God has given us, but the global warming alarmists are using gloom-and-doom, fear-based tactics to advance their environmentalist agenda which will eliminate job opportunities and slow economic growth."
You can see my reply to his disingenuous portrayal of "weathercasters" (that would be meteorologists) and how he tries to misrepresent climate science on my blog, here. But the thing that stands out about this statement is the total lack of science, reason, or understanding.

He is absolutely wrong on climate change. Climate science is based on known scientific principles. There is no question about the science. What remains is an obvious example of using religion to damage the world and the people in it.

Jim Inhofe gives us the perfect example of where the usage of religion has gone wrong. This is exactly the type of danger that religion poses to the rest of the world. Ultimately it doesn't even matter whether he believes what he is saying or not. The simple fact that there are people out there that will believe what he is saying because of their shared religion is what makes him and religious people like him as dangerous as someone actively trying to destroy the world and everything the human race has built.

Slap a generator on that spin

I can't help but wonder whether Jim Inhofe actually believes the things he says or not. If he believes the things he says then he is one dangerous person to have in political power. If he doesn't, then he is even more dangerous because he has no interest in the truth or the people that the truth will hurt.

In a statement Jim Inhofe gave to the U.S. Senate Comitee on Environment and Public Works: "Climate Change: It’s Happening Now." he said:
Most meteorologists agree [with Allison MacFarlane, when she was asked about whether she thought the tornadoes in Oklahoma or Hurricane Sandy were extreme weather events, she said, “I would not call these events extreme. I would call them normal."]. A recent study by George Mason University reported that 63% of weathercasters believe that any global warming that occurs is the result of “natural variation” and not “human activities.” That is a significant two-to-one majority.
Here is a quote from the study (pdf) that Sen. Inhofe is referring to:
Weathercasters hold a wide range of beliefs about global warming.
Survey participants responded to a variety of questions assessing their beliefs in and attitudes about “global warming,” questions that have been used previously in our public opinion research. More than half of our respondent (54%) indicated that global warming is happening, 25% indicated it isn’t, and 21% say
they don’t know yet. About one-third (31%) reported that global warming is caused mostly by human activities, while almost two-thirds (63%) reported it is caused mostly by natural changes in
the environment. Half indicated that they have thought “a lot” about global warming, and a large majority said they are fairly or very well informed about the causes of global warming (93%), the consequences of global warming (89%), and the ways to reduce global warming (86%)—numbers that are much higher than public responses to the same questions. Over half of weathercasters indicated that humans could reduce global warming (58%), and that the U.S. should reduce greenhouse gas emissions regardless of what other countries do (63%). Almost half (47%) felt they needed some or a lot more information before forming a firm opinion about global warming, and almost one-third (30%) said they could easily change their mind about global warming. Just over one quarter (27%) agreed with the statement by a prominent TV weathercaster: “global warming is a scam.”
The picture that the study paints -- even the paragraph that Sen. Inhofe quote mined -- shows that meteorologists are geared more toward doing something about global climate change (or global warming if you prefer) than are geared toward ignoring it. And only about one in four think that "global warming is a scam".

But there is more to this study than that. The study was done to gauge what the meteorologists knew about global climate change. It is climate scientists that are doing the science on global climate change, not meteorologists. This was a study to see if the meteorologists were keeping up with what the climate scientists were learning. And while the study shows that the meteorologists are better informed as a group that the average American citizen, they still have a long way to go.

The very next paragraph from the study demonstrates the problem. Sen. Inhofe would have been much more truthful to report this:
Only one third of TV weathercasters believe that there is a scientific consensus on climate change. Despite the strong scientific consensus among climate scientists, almost two-thirds (61%) of TV weathercasters think there is a lot of disagreement among scientists about whether or not global warming is happening. Perhaps partly as a result, 79% of our respondents indicated that coverage of climate change science must reflect a “balance” of viewpoints just as coverage of political or social issues are covered. Prior research conducted by others, however, has shown that “balanced” news coverage about climate change is misleading in that it tends to give audience members the false impression that there is a lot of disagreement among scientists about whether or not global warming is happening.
Yes, global warming is happening. The science of the cause of global warming isn't new. The science has been well understood for quite some time. Greenhouse gasses make the atmosphere warmer. No one except the scientifically illiterate and the completely deluded would deny that. The deeper Jim Inhofe digs trying to find reputable people that believe the same way as he does, the more he will look like the bottom feeder that he is.

But you don't have to take my word for it. The study (pdf) isn't that long, and the findings aren't difficult to understand. Go read the study and you will discover just how much Jim Inhofe has to quote out of context to even bend the non-scientists to his viewpoint.

Where "Scientific" Skepticism Fails

Despite their claims, they can't divide science up into science they like science that doesn't count.

One of my pet peeves regarding the skeptical community is the belief that some of them foster regarding science and empiricism. They try to present themselves as a community that tests every claim in the universe that can be empirically tested. And if they test every claim that can be empirically tested, then anything that they don't test must, somehow, be outside the realm of empirical science. That belief, of course, is bullpucky. Contrary to claims made by various skeptics, they seem to only be interested in a small portion of all the things that can be scientifically tested.

Daniel Loxton wrote a piece at Skepticblog regarding the lack of overlap between the skeptical movement and atheism:

Skeptics like Steven Novella insist that sticking to the realm of science is “about clarity of philosophy, logic, and definition” rather than strategic advantage or intellectual cowardice, but some critics find this position unsatisfying—or even suspicious. (...)

I have divided this paragraph into two pieces so that I could separate out the supposed claim from the actual claim without making it look like I was trying to take his words out of context. As for the above quote, I can see that the supposed claim is that strictly adhering to science is a matter of clarity while others (atheists I presume) claim it is cowardice. I, personally, don't know anyone that thinks this. I could be wrong since atheists think for themselves, I doubt that this is the predominant view that atheists hold of skeptics.

(...) What are we to make of accusations that skepticism’s “testable claims” scope is a cynical political dodge, a way to present skeptics as brave investigators while conveniently arranging to leave religious feathers unruffled? Like the other clichés of my field (“skeptics are in the pocket of Big Pharma!”) this complaint is probably immortal. No matter how often this claim is debunked, it will never go away.

Here is the part that I really have a problem with. Skepticism doesn't include all testable claims. Skepticism only includes a minor subset of testable claims while at the same time actively denigrating people that work in the broader context of science.

Before I upset too many skeptics, I need to point out that this isn't intended as a broad brush claim. There are plenty of skeptics that don't limit themselves to a narrow subset of science. There are also plenty of skeptics that welcome atheists into their ranks. But there are enough skeptics that want to limit skepticism to their narrow definition of science that a reasonable portion of atheists no longer feel comfortable claiming common cause with skeptics. And it is this divide between skeptics and atheists that is frustrating since the overlap between the two communities is so vast.

In his post Mr. Loxton talks about the charges he believes are leveled against the skeptical community. I have never heard these charges myself, but that doesn't mean that some atheist has made them at some point in time. He believes skeptics giving any sort of special pass to religion is inaccurate. He goes on to say that skeptics investigate any claim that can be investigated regardless of whether religion is involved.

Now, here’s what actually is true: scientific skeptics investigate claims that can be investigated (religious or otherwise) and we set aside claims that cannot be investigated (again, religious or otherwise). The “religious” part is irrelevant. It comes up on both sides of the testability equation, so just cross it out and forget about it. The only relevant distinction is simply whether empirical evidence is possible. If we can’t collect evidence, then tough—we can’t. If we can collect evidence, then we do, regardless of whom that evidence may offend.

But is that true? I would submit that it is not. I am not arguing that the skeptics intentionally provide cover for religion, but I do believe that they don't test religious claims unless they are blatantly, obviously, and unquestionably fraudulent. What if a religious claim falls within the bounds of science to the same degree that a non-religious claim would? Are they actually treated the same way?

Imagine a hypothetical person walking up to a skeptic and saying that they believe in complimentary and alternative medicine. What do you suppose the skeptic would say? Since many of the skeptics I know take an active interest in debunking CAM (complimentary and alternative medicine), I would assume that they would follow up with a few questions or assumptions and begin to debunk the crazy claims that many of people in the CAM community have put forward.

Notice that our hypothetical person didn't claim a belief in any specifics that could be debunked. They didn't claim to believe in homeopathy, magneto therapy, or acupuncture. Yet CAM itself falls outside of the skeptics specifically defined bounds. It, in and of itself, can not be empirically tested because it isn't clearly defined. While there might be several things that fall under the CAM umbrella that can be tested, CAM itself can not. Regardless of this fact, I have never seen a skeptic step away from CAM scratching their head and saying that they must remain agnostic about CAM since it falls outside of empiricism.

Now let's take a look at religion. People often say that they believe in a god. There are no shortage of them in the United States or the world for that matter. God, at least at this point in the conversation, is just as much of an umbrella concept as CAM. Since it isn't defined, their god could be an alien hidden under a rock on the far side of the universe that has no interaction with us at all and no ability to pull itself up out of the mud.

Raise your hand if you think this is the kind of thing that religious people are talking about with respect to their god. Yet despite not even scratching the surface of the god hypothesis, many skeptics gladly shrug and assume an attitude along the lines of 'I can't test it, so happy proselytizing'.

Those of us that don't want to ignore a specific claim that something exists have to clarify the claim. We ask a question. Do you, as a religious person, believe that a child was born to a virgin that was the son of your god? Since the most common response in the United States would be "Yes!", we'll assume that answer from the theist. Despite their answer, everything we know about science says that this is impossible. Every test that we have ever observed has demonstrated that women don't become pregnant spontaneously.

So we ask another question. Do you believe that Jesus was crucified and came back to life at a later date (usually considered three days)? Everything we know about science says that humans don't come back from the dead. While there might be some leeway about where exactly the line is that makes a human dead, once they cross that line, they don't come back. And even when they do come back after tens of minutes submerged in frigid water, it is always with heroic measures.

Another question: do you believe that your god interacts with humanity by answering prayers? We have actually tested this repeatedly under controlled circumstances. We haven't ever observed a prayer being answered.

Another: does your god interact with the world in any way? Assuming the answer is yes, then the interactions can be tested empirically. Theoretically, if a fly farts on Mt. Fuji then we can demonstrate that interaction with the world. The more grandiose the interactions, the easier they are to test; yet no evidence for a god has ever been found.

I will, of course, grant that absence of evidence isn't evidence of absence. Regardless, absence of evidence when we have tested for it repeatedly is at least on par with the absence of evidence for Bigfoot or the Loch Ness Monster.

Atheists often see skeptics trying to define empiricism and science specifically to suit their purpose. When skeptics talk to someone that believes in Bigfoot, they say that they have reviewed the evidence and found no proof that the creature exists. Skeptics then tell the world that there is no reason to believe in Bigfoot unless new evidence is presented to support the case. Yet when atheists tell someone that believes in God that we have reviewed the evidence and found no proof that the creature exists, and we tell people that there is no reason to believe in God unless new evidence is presented, we are accused of operating outside the of the confines of empiricism.

If, as skeptics, you want to avoid religious questions, that is your choice; however, when atheists use science to empirically test religious claims, you don't get to claim that we are doing skepticism wrong without looking like you are, indeed, giving religion a free pass for some reason.

The Possibility That Religion Is True Is Vanishingly Small

It is so unlikely that religion is true that the possibility should be ignored by everyone until such time that any real evidence is presented.

Gary Marcus posted an article in the Newyorker concerning science, religion, and faith.
(...) Any agnostic is free to believe that his favorite religion has not yet been completely disproven. But anyone who wishes to bring science into the argument must acknowledge that the evidence thus far is weak, especially when it is combined statistically, in the fashion of a meta-analysis. To emphasize the qualitative conclusion (X has not been absolutely proven to be false) while ignoring the collective weight of the quantitative data (i.e., that most evidence points away from X) is a fallacy, akin to holding out a belief in flying reindeer on the grounds that there could yet be sleighs that we have not yet seen.
 This is one of several prongs that is useful in understanding religion. Religions have been looked at an enormous amount over the course of human history. Every time we have looked at them, they have failed. The accumulation of all those failures add a statistical weight to just how unlikely it is that any given religion is true. And all that is before we even weigh any claim from a specific religion.

The idea that any religion is true is so miniscule that it would take an enormous amount of verifiable evidence to swing the scales back the the idea that believing in religion was scientifically reasonable.

HIV Positive Baby Cured With New Medical Regimen

On Sunday March 3, 2013 Medical researchers announced that a baby in Mississippi was 'functionally cured' or HIV. There is no doubt in my mind that this fantastic news will be trumpeted from the rooftops -- as well it should -- of the community that I follow. This is yet one more step on the road to progress that I have seen in my life.

I was in high school when the AIDS crisis was first known to appear in the United States. All around me were people that were using their religion to say that AIDS was a punishment from their god for being homosexual. It was then that I realized just how petty and dangerous religion could be. It also means that the AIDS/HIV problem has carried a special interest to me.

When no one knew the cause of AIDS, the religious people would tell anyone that would listen that AIDS was caused directly by the hand of their god. God had finally had enough with those evil gays thumbing their noses at him. Later, when HIV was found to be the cause of AIDS, the Christians still claimed that AIDS was the work of their god. HIV was just the mechanism that he used to cause AIDS. Since humans couldn't cure a virus, it didn't matter that their god used a virus to punish people that he had condemned. It was also very effective since the only way to get AIDS was to do that icky homosexual stuff. It didn't matter that heterosexuals were also being affected, as long as it continued to be perceived as a gay disease.

Now a HIV/AIDS infection seems to have been cured twice: once with a functional cure, and once with a possible 'sterilizing cure'.

CNN reports:

Dr. Katherine Luzuriaga, an immunologist at the University of Massachusetts who worked closely with [pediatric HIV specialist Dr. Hannah] Gay, called the developments fascinating, including the fact that the toddler was found to have no virus in her blood even after her mother stopped giving her treatment for eight to 10 months. 
"This is the very first case in which we've conclusively been able to document that the baby was infected and then after a period of treatment has been able to go off treatment without viral rebound," Luzuriaga told CNN.

This is yet another case where Christianity originally showed the strong prejudices it holds only to be surpassed by scientific knowledge and genuine human compassion. Yes, there is no doubt in my mind that a hundred years from now the Christians of that time will be able to look back, see the horrors that were committed in the name of their god, and try to distance themselves from it. It has happened before with every inhumane stance that religious people have taken. It has happened with out of wedlock mothers, mental disorders, physical ailments, and virtually every disease that had an unknown origin. That is what makes Christianity dangerous as it has been practiced: instead of being a force of good, it usually starts as cover for bigotry and prejudice. It is only after the rest of society leaves them behind that they begin to come around and act like decent, caring, respectable human beings.

Visualizing the Reality of Evolution

I am always amazed when people reject something that they don't want to believe. If your entire basis for believe in a god is that evolution couldn't have happened, then you should at least check to make sure that evolution hasn't been proven in the lab. And that is exactly what we find: evolution has been observed under experimental conditions in the lab. There can be no question. We can never go back to a world where it is intellectually honest to question whether evolution is real or not.
Richard E. Lenski at Michigan State University has been running an experiment to watch how bacteria evolve. He started with a single E. coli bacteria and used its descendants to start twelve different laboratory populations. He then watched these bacteria change over time.

But sometime around the 31,500th generation, something dramatic happened in just one of the populations - the bacteria suddenly acquired the ability to metabolise citrate, a second nutrient in their culture medium that E. coli normally cannot use.
Indeed, the inability to use citrate is one of the traits by which bacteriologists distinguish E. coli from other species. The citrate-using mutants increased in population size and diversity.
"It's the most profound change we have seen during the experiment. This was clearly something quite different for them, and it's outside what was normally considered the bounds of E. coli as a species, which makes it especially interesting," says Lenski.

This is a perfect example of evolution. A population changes over time through reproduction to live better in their environment. This is exactly what the E. coli bacteria did, and because it was observed in a lab, there are samples saved from every stage so that we can go back and rerun the experiment and see exactly what is happening.
Now I know that some creationists will claim that this is an example of micro-evolution. And while they believe in micro-evolution, they don't believe in macro-evolution. But the only difference in micro-evolution and macro-evolution is time. Macro-evolution is simply multiple different micro-evolution events stacked on top of each other.
It might be difficult to imagine the time frames involved in evolving something from a bacteria to a more complex (notice that I didn't say advanced) form of life.
Let's say that we put a marker in our back yard. For every year of time that passes, we are going to measure off a half inch. How long did it take for the E. coli bacteria to evolve to a different form of bacteria? About 20 years, or 10 inches by our scale. How long has life been here on Earth? Using our same scale it would be the entire distance around the Earth. Over that length of time, it is difficult to imagine that much more complex forms of life wouldn't evolve.
