Causal test?
But what were their chocolate habits before winning? Did they eat more than was typical for their cohort then? Or is chocoholism a side effect of winning a major scientific prize?
A California researcher has discovered a strong correlation between chocolate consumption and the degree of smarts that results in being awarded a Noble Prize. In "Chocolate habits of Nobel prizewinners", published in Thursday's edition of Nature, Beatrice Golomb of the University of California, San Diego, notes that of the 23 …
The Swiss have the most award recipients, and eat the most chocolate. The next several countries in both categories enjoy relatively open borders with Switzerland, enabling cross-pollination opportunities.
Check your genealogy: if you have Swiss blood in you, you may be prone to eating a lot of chocolate, or to performing extraordinary tasks solely for small quantities of metal and a sizeable quantity of dosh.

This was looked into on more or less on radio 4 by Tim Harford some months ago, and I think the guys at the following blog showed similar relationships between car crashes and Nobel laureates (and chocolate consumption to serial killer rates);

The graph seems to be more like a combination of general standard of living combined with importance of chocolate culturally in terms of local confectionery and pastry preferences, plus some added random elements. To me that's Occam's Razor in action: we already have a very simple reason of why we see this distribution. No need to find arcane reasons!
It's true that one needs to explain Belgium but their Burgundian attitude might conflict with Nobel aspirations, at times :-)
I'm sure that once you have a Nobel prize, you pretty much dont need to falsify data to gain benefit; benefits will flow regardless of how mundane your subsequent work is. Why put a Nobel-sized reputation at risk with fakery?
