>the not-jumping-out experiment

you mean cooking a frog? I'm not aware that the phrase refers to an experiment, rather a cooking pot, and anything with its brain removed is dead anyway?

anyway, the same can equally be said for flies. if you swat fast at a landed fly it will notice and fly away; however if you bring the swatter close slowly and evenly the fly will allow it close enough that there's no escape

If you slowly boil any animal with a brain that can move out your boiling recipient, it will move out once the temperature is uncomfortable, way before any danger.

The expression always seemed dumb to me, but now that I know where it came from, I'm vindicated.

where are you suggesting it came from?
