So you just time if the dog stays there for long enough and presto, the odd cat is out. It's quick, it's dirty, it's not the best solution but it works.
Basically by ignoring all the shorter visits it's as if the dog never visited on it's own. |
Exactly - and that is not what Wiseman did - he took the time of the first visit to the window as the only data! I am sure Rupert's data could be analysed the way you suggest - my point is, that in any experiment you absolutely have to take into account possible sources of noise, and that is what Wiseman didn't do - basically because the null result was fine by him!
