Or, perhaps, autism and rainfall.
Children who live in areas with heavy rainfall could be more likely to develop autism, scientists claim.
Well, yes. They have indeed found a correlation here. But it\’s rather difficult to take them very seriously. This is a revision of an earlier set of papers which claimed that more TV watching led to autism. The link? They assumed that kids would watch more TV when it was raining, so they measured rainfall and autism and found the correlation.
But now they\’re slightly stuck. They can see the correlation, but can\’t explain causation. No real theory at all.
