Since there have been a few heated exchanges between people I’ve both grown to like and respect, I thought it was time for some light-hearted relief. I have a sense that some (not those who regularly comment here of course :-) ) have a rather simplistic view of how science actually works. They think that you design your experiment; you collect your data; you analyse your data using procedures that you specified before the project started; you don’t deviate from your original plan/strategy; you publish everything, warts and all.
There are areas where that may be close to how it works (or should work) but there are others where it is a far too simple perception of how science really works. The illustration below is much closer to actual scientific reality (cartoon from Twisted Doodles).
