Default Modus tollens

"One study found that the vast majority of scientists
drawn from a national sample showed a strong preference
for "confirmatory" experiments. Over half of these
scientists did not even recognize disconfirmation (modus
tollens) as a valid reasoning form! In another study the
logical reasoning skills of 30 scientists were compared
to those of 15 relatively uneducated Protestant
ministers. Where there were performance differences, they
tended to favor the ministers. Confirmatory bias was
prevalent in both groups, but the ministers used
disconfirmatory logic almost twice as often as the
scientists did." ~Michael J. Mahoney, Publication
Prejudices: An Experimental Study of Confirmatory Bias in
the Peer Review System Cognitive Therapy and Research,
Vol. 1, No. 2, 1977, pp. 161-175.

This is one study done in 1976. I'm not certain where they found fifteen relatively uneducated protestant ministers. Most of the protestant ministers I know have Masters degrees, so right away, I'm suspecting something odd is going on here.

More importantly however, this is not an alternative theory, it is not even about astronomy or astronomers. You seem to be simply exploring a way of bashing mainstream scientists.

Did you have some other goal? Is there a reason I shouldn't move this to Off-Topic BABBling?

You have just proven this paper to be correct.
You have allowed your bias to color a discussion of the premise of this paper.

This is posted in the context of "bashing" ATM theories. Also standard science says there is nothing wrong with the peer review system, so this is definately an ATM topic. As the paper says, scientists introduce bias variables into the peer review system.

Upriver, you seem to have missed the question.

How is this paper related to astronomy, the universe, stars, etc? Looks pretty off-topic to me.

Perhaps its relevance is indirect: Peer review and the scientific method are both used by astronomy. The paper also reminds me of the following:

I suppose you might make the argument that this could go in the "General Science" section.

But, I look at this and ask ... your point is?

We've gone over this before. Scientists aren't Vulcans. They are human like anyone else, and will have opinions. Also, some fields are more political than others, especially in biology/genetics, ecology/climate, and anything that touches on real-world nuclear applications, civilian and military.

So fine, it ain't perfect. But the ultimate goal is science, so whatever the faults of the mainstream may be, it doesn't give against-the-mainstream folks a free pass. They still have to do the science. They still have to show the math.

So, again, what's the point? Especially when discussing a subject like astronomy, where the political/religious controversy is minimal.

Unless and until someone can make clear that this is specifically about astronomy (etc), I think the home for this is 'General Science'. And I've also decided to be decisive (a mod, or admin, can always move it back, if warranted).

I must be atypical then...as the work I've done that is enroute to being published (one is actually in review now) tends to be just such work. I really do prefer checking to see if people are wrong.

Example of something I've done: The literature says various types of quasars vary more or less than other types, the predictions are based upon the models used to explain the quasars behavior.

The work I've done found that specific quasars that are clearly defined types, vary in ways contrary to these predictions (basically they all vary abou the same amount)...as such the common wisdom is incomplete (if not just wrong).

Part of the problem with Modus Tollens is that many scientific experiments and predictions aren't very clearcut. The prediction may be incomplete, to general, and other aspects may be true. Just that particular manifestation is wrong.

Take that quasar thing as an example. It doesn't mean the models are completely wrong, perhaps they are only misapplied, or a couple of models can be replaced by a single model.

Also, most people I talk to admit there are problems with the peer review system. Specifically the peers are human. They are opinionated, have motives, and have differing levels of experience in various fields.

However, nobody has really figured out a better way of handling the publishing of scientific papers.

Thank you. That all I wanted. I think this also applies to us as we try to figure out whether someones theory has merit but is incomplete.

I only monitor the "Against the Mainsteam" (formerly Alternate Theories). I felt the original post and the links provided by iantresman were excellent -- it is really something to worry about if you EVER expect to take a new theory INTO the Mainstream. I am sorry to see this moved, but I guess I will add General Science to my watchlist unless it becomes too time consuming. upriver and ian -- many thanks.

I think there have been several good suggestions about improving the system, but few have been taken up because (a) there is no incentive (b) mainstream looses its "power" (hence money).

How many people are even aware of suggestions that might improve peer review? And I think that sums it up. People don't care because they are content with the status quo.

I think it is interesting that although "science" aims to be impartial, open, and having a number of checks and balances, it doesn't apply the same criteria to the very system that publishes science. Peers are often impartial (because they have their own competing theories), closed (peers are anonymous and unaccountable), and there is no opportunity for checks and balances.

Ian Tresman

Well, present a suggestion for improving it that you think is good, and we can discuss it.

I note that, of the specifics I checked (in Campanario and Martin 2004 paper; there may be some in the four links I haven't checked yet), only two in the field of astronomy are cited ("A sample of well-qualified challengers to orthodox physics"):
- Arp
- Van Flandern
(there are three in hard-core physics: Assis, Marmet, and Spenser).

If this is the strongest case which you can present, then I for one would conclude that there would indeed seem to be little incentive to work for change.

Why? Because, in astronomy at least, it 'ain't broken' (in any measurable way).

Didn't we have a thread, in either BA or UT, where we discussed this topic, from a purely planetary sciences, astronomy, astrophysics, cosmology perspective? Why not revive that, to continue our discussion, focussing on what we members are most interested in (and, likely, knowledgable about)?

If you think there are suggestions out there, lets hear them. They tend not to work out to well.

What makes astronomers holier than thou?
Maybe you have not tested it. Put together a fake study
using an ATM theory and then one using a mainstream theory
and see which has the greater % of rejections. You
could find an ATM theory that is true but not widely
accepted.
I'm not not bashing, I'm just stating the obvious.

Because nature doesn't lie. People do. The "human" sciences are behind the physical sciences (such as physics, astronomy, and chemistry) in their quantitative rigor. Not a knock on these fields, that's just the nature of the beast so far.

And despite your disclaimer, you are bashing practicing scientists with your statements. And no, they are not obvious. If the ATM theory, as is true for most of them (especially electric universe ideas) makes no quantitative predications that can be compared to experiment and the mainstream theory does, and matches those observations well, why are you surprised the former is rejected. I have yet to see an ATM idea proposed on these boards that would meet even the loosest requirements for acceptance.

Would Crichton's idea be useful of making the peer system "public", complete with names and comments of the reviewers? It could get rid of some of the more "politically" motivated comments (maybe Crichton wasn't the first to suggest this, but I first read it in his awful novel State of Fear).

Cheers.

Might be a problem, too: Suppose two researchers are friends or, worse, reaearcher No. 1 is in some position of dependence on researcher No. 2 (wants him to give a favourable opinion on a grant; would like No. 2 to accept him as postdoc; No. 2 is on the board which decides about No. 1's tenure; etc.). Now No.2 submits a paper which is junk, and No. 1 is chosen as a referee. Only if he remains anonymous can he dare reject the junk paper. In an open system he would shoot himself in the foot by writing a rejection.

So the main danger with open peer review is massive nepotism - the greater danger, if you ask me. Of course, anonymity can be abused, too, but it is the oly environment in which one can be frank without the fear of recrimination.

In astronomy at least, it's possible to "figure out" who's the referee just by the comments they make.

Then again, astronomy is a suprisingly small field in terms of researchers. So it's likely you know 90% of the people in your particular field.
