My new column is up this week, and is a response to the July 2012 issue of Popular Science which includes a long, unbalanced attack on skeptics, without once addressing their scientific arguments.

I thought I knew what “science” was about:  the crafting of hypotheses that could be tested and refined through observation via studies that were challenged and replicated by the broader community until the hypothesis is generally accepted or rejected by the broader community.

But apparently “popular science” works differently, if the July 2012 article by Tom Clynes in the periodical of that name is any guide [I will link the article when it is online].  In an article called “the Battle,” Clynes serves up an amazing skewering of skeptics that the most extreme environmental group might have blushed at publishing.  After reading this article, it seems that “popular science” consists mainly of initiating a sufficient number of ad hominem attacks against those with whom one disagrees such that one is no longer required to even answer their scientific criticisms.

The article is a sort of hall-of-fame of every ad hominem attack made on skeptics – tobacco lawyers, Holocaust Deniers, the Flat Earth Society, oil company funding, and the Koch Brothers all make an appearance.

Thousands of words about critical issues like Heartland Institute's funding, but less than two dozen dedicated to dismissing skeptic's scientific concerns.  And that is before we get to outright journalistic fraud, as the author attempts, for example, to lay blame for Obama Administration financial audits of climate scientists on, you guessed it, skeptics. Read it all

I thought this quote, via Reason, from anti-smoking advocate Michael Siegel is representative of how many pseudo-scientific advocacy groups work today:

In the 20 years that I was a member of the tobacco control movement,
I was led to believe that there were only two sides to any anti-smoking issue:
our side and the tobacco industry side. Therefore, anyone who disagreed with our
position had to be, in some way, affiliated with the tobacco industry. I was
also taught to respond to their arguments not on any scientific grounds or on
the merit of their arguments, but by simply discrediting the person by attacking
their affiliation with the tobacco companies.

As I have found out over the past two decades, there are a lot of
individuals who disagree with a number of positions that the anti-smoking
movement has taken (interestingly, now I find myself to be one of them). And not
all of these individuals are affiliated with, or working for the tobacco
industry. As individuals who are not part of a tobacco industry campaign, these
people are entitled to express their opinions and their arguments really deserve
to be addressed on their merits. At very least, anti-smoking organizations and
advocates should not attack these individuals. Attacking their arguments is
legitimate, but attacking the individuals, in these cases, is not.

Take this statement, substitute global warming for anti-smoking and oil industry for tobacco industry and the statement still works just as well.

Update:  For another example, see the debate over child seat efficacy at the Freakonomics Blog.  A couple of researchers studied data on injury rates of kids in car seats vs. kids in seat belts, and found little incremental benefits of seat belts.  Note their desire to find the truth under the numbers:

What is more puzzling to me is why my results and Heaton's both suggest very
little injury benefit of car seats, but the medical literature often finds 70%
(!!) reductions of injuries with car seats relative to seat belts. We find
reductions that are an order of magnitude smaller. They use very different
methods -- surveying people in the weeks after crashes for instance -- but still
it is really a puzzle. Which is why, when you read my paper, I am extremely
cautious in interpreting the injury findings.

I hope that the medical researchers, Heaton, and I can all work together to
try to make some sense of the conflicting results being generated by these
different methodologies to resolve this important question.

Seems like a reasonable scientific attitude.  Now (via Marginal Revolution) here is the response of a child seat "activist" to their findings:

Their [Levitt and Dubner] conclusions stand in stark contrast to the existing
body of scientific data that support current child restraint recommendations,
and are, in our opinion, irresponsible and dangerous....We hope that this
misleading article does not cost a child his life.

In other words:  Open scientific debat = killing children.  Levitt and Dubner must work for Haliburton.  Levitt has an update to the whole debate here.

Over the last year or so, ad hominem political arguments have really begun to drive me crazy.  I don't think that they are any more prevalent, but since I have begun blogging and tried to really get underneath the factual underpinnings of certain issues, these ad hominem arguments have become more irritating.

What do I mean by ad hominem arguments?  Here are several examples:

Ad Hominem Classic

The classic Ad Hominem attack is one that substitutes a (mostly) irrelevant personal attack on the author of an argument instead of logically or factually disputing the argument itself.  I could pick from about a thousand examples a week from the blogosphere, but a good recent example were conservative attacks on Robert Byrd's admittedly over-the-top defense of allowing filibusters for judicial nominees.  Almost every response I saw to Byrd was careful to remind readers that Bird was a KKK leader forty plus years ago.  Though certainly unsavory, it is unclear how being a KKK member is relevant to the argument about the filibuster rule (the only real connection, though irrelevant to refuting Byrd's arguments, is that Byrd used a filibuster rather famously to try to head off passage of the Civil Rights Act in the early 60's).  If anything, one might argue that Byrd's historic white supremacist activities might make him more rather than less favorable to judicial nominees.  If anything, the one relevant fact about Byrd that might have some bearing on the argument is that he is often considered a constitutional expert, and has been cited as such a number of times by Republicans when it suited his purpose.

Ad Hominem Shorthand

This is a staple of Blog comments.  Examples include "Bush is a Fascist", "Bush is a Liar", "They're Moonbats" etc.  These arguments usually do nothing to enhance an online argument.

Ad Hominem Motivation / bias

A good example is "of course you oppose abortion - you're Catholic".   While bias or group affiliation may be a pointer to potential weaknesses in a person's argument, they are not weaknesses in and of themselves, and pointing out these biases or affiliations does not constitute refutation of an argument.

Ad Hominem Protected Group Status

This is the reverse of the one above.  Rather than trying to refute the argument by pointing out the group affiliation of the other person, you are instead trying to short-circuit the argument by taking advantage of your own group affiliation.  A good example is of those in "protected" groups (blacks, women, etc) responding to arguments by saying you are just being racist / sexist.  This is a very popular tactic on campus's, where members of protected groups use campus speech codes to try to declare certain arguments illegal "hate speech", thereby eliminating the necessity of actually having to respond to or refute the argument.

Ad Hominem Source of Funding

This charge is increasingly prevalent in the blogosphere, as both liberals and conservatives accuse the other of "astroturfing", or offering political opinions for payola.  While source of funds for writing and research are important points of disclosure, the fact that an argument has been subsidized by this or that group does not automatically negate the argument.  For example, global warming activists love to point to studies that refute warming claims by claiming the study was paid for by the power industry, or the oil industry, or whoever.  While this should make one skeptical, it does not constitute sufficient refutation of logic and data, though it is often used that way.

Ad hominem guilt by association

This is perhaps the weakest of all ad hominem attacks.  It attempts to undermine an argument not by pointing out flaws in the person making the argument, but by pointing out flaws in other people making the argument.  For example, conservatives like to dispose of anti-war arguments by pointing the the wackiest of anti-war protesters, and saying "see, you are just one of these moonbats".  More recently, liberals have tried to undermine reasonable people arguing for not removing Terri Shiavo's feeding tube by pointing to how unsavory and unreasonable other people have been in the same cause.  Can't we just admit that for any argument one wants to make, there is someone out there who agrees but who one would not want to be associated with.

*    *    *

Anyway, I probably left a few out.  I don't know if it is still the case, but in British legal arguments there used to be a distinction between hard evidence directly refuting an argument and "pointers", or items that might cause one to be suspicious of the opposite party's arguments, but which don't actually constitute proof.  In this context, ad hominem arguments can be thought to sometimes provide a useful pointer, but they should never be mistaken for a true refutation of the facts.
