Time to re-read Kuhn's The Structure of Scientific Revolutions

The book Stress Analysis of a Strapless Evening Gown had an essay titled, IIRC, On the Nature of Mathematical Proof. The only ones I remember were Proof by Blatant Assertion and Proof by Lack of Counterexample. I wonder if they had a Proof by Selective Data.

There's an old joke about an astronomer, a mathematician and an engineer trying to prove that all odd numbers are prime. (We have to take 1 as prime for the purposes of the joke.) The astronomer says, "1's prime: yes, all odd numbers are prime. The mathematician says, "1's prime, 3's prime, 5's prime, 7's prime: yes, by induction all odd numbers are prime." The engineer says: "1's prime, 3's prime, 5's prime, 7's prime, 9? 11's prime, 13's prime, 15? 17's prime, 19's prime: yes, all odd numbers are prime; 9 and 15 are experimental error."

[(myl) There's a crueler version of the joke, in which one of the participants says "1 is prime, 3 is prime, 5 is prime, 7 is prime, 9 is prime, 11 is prime, ..." The inattentive or arithmetically challenged participant can be the engineer, the physicist, or the mathematician, depending on your prejudices.]

More variations than at which a stick could be shaken:

Sorry, coudn't figure out how to make the link live, given the short attention span I have on Friday afternoons….

Well, blow me down–it just worked!

Come on. This is totally legitimate way of thinking. The nature (or Nature) is awfully complicated and, unless you are trying to find a theory of everything, your particular theory will sometimes work and sometimes don't. Now, if you dreamed of some interesting situation, say that under certain conditions the evolution will go along the Lamarckian lines, why not to search for something that actually behaves like this.

@Faldone: I assumed that book must be a retitling of "Abandon Walk in Science", which certainly contains both of those articles. But it appears to be a different compilation.

@D.O. I might agree if the question had been, "Do you have any data relevant to my theory?"

But the question as posed suggests he is looking for data that will support his theory and not data that might falsify it; that is The Way of the Pseudoscientist.
