I googled for it but didn't find any evidence for pigs killing people.
Googled it too. You need to expand "pigs" to include "wild boar".
Still this "six times as many death from pigs as from sharks" sounds suspiciously like an urban legend, the precise multiplier implies that there should be a well known source and not finding it is a hint. The numbers are small enough that the ratio should be all over the map.
A monthly thread for posting rationality-related quotes you've seen recently (or had stored in your quotesfile for ages).
ETA: It would seem that rationality quotes are no longer desired. After several days this thread stands voted into the negatives. Wolud whoever chose to to downvote this below 0 would care to express their disapproval of the regular quotes tradition more explicitly? Or perhaps they may like to browse around for some alternative posts that they could downvote instead of this one? Or, since we're in the business of quotation, they could "come on if they think they're hard enough!"
