Correlation does not mean causation

Chocolate makes you brainier! You can envision the screaming over-hyped headlines of the red top media on this one. A recent study suggests that more Noble prize winners consume high levels of chocolate than non- winners.

Realistically there is probably no correlation between the two and the BBC article here reflects that well. It is interesting that this sort of 'report' has come out though as each year around this time in the run up to Christmas there is always a surge in medical evidence supporting all sorts of supposed benefits to be gained from chocolate and alcohol (What is the provenance of these reports are they all sponsored by Cadbury & the Bordeau marketing board?).

Always fun, always this time of year - look out for the coming slew of health promoting benefits from these products and remember the argument against correlation and causation!
