Anyway, here's an interesting article about the traditional theory of seasickness (basically, the result of our senses not giving consistent information) and why that don't make no sense. The contending theory is offered to make up for the alleged inconsistencies in the traditional theory:
1) It relies a notion of sensory inconsistency where one of the senses is giving 'wrong' information, but because it is impossible to determine which sense is 'wrong', the theory is unfalsifiable.
2) The traditional theory has been dreadful in predicting who will suffer from seasickness in space. (Just 30%)
Instead, the contending theory wants to put the cart before the horse, and say 'No, postural instability isn't a symptom of seasickness, it is the cause of it.' As evidence, the article cites studies that show simply increasing the stance one takes (i.e. how far one's feet are apart) reduces the sickness symptom.
