It is quite easy to spot the difference between "political scientists" and "scientists".
The Poli Sci types are always on about saliency or lack thereof --- the boffins never ever are.
Never never never never ever are.
Any theory that claims that the stock market or the economy or the weather is virtually impossible to predict accurately can be tested - for free - by the seven or eight billion of us.
The results affect all of us - daily - and we ourselves can conduct the experiment.
But most of the supposedly epoch breaking experiments, the type that scientists love to bang on about, we can only take on the word of well educated journalists making sense of long articles in journals like Nature or Science.
We can't even follow the logic of a written report on a written report of an experiment, let alone conduct the experiment ourselves and besides nothing it claims to report seems to make a bit of difference to our lives.
