More seven

Clearly a good month for the rule of seven, with another one popping up from the University of Oxford this morning.

Probably time that I produced a consolidated spreadsheet of them all, pivot tables and all.

Probably time also that I checked that the difference between the frequency of seven events and that of, say, four, events is as significant as I think it is. Is looking out for sevens biasing my perception of their relative frequency? Is the 'p' value of the sevens actually good enough? The 'p' value which something I read in the last few days - so either the Guardian or the Economist - suggests we are taking rather too seriously.
