Data harvesting, Facebook, and the “10 year challenge”.

To be fair, I haven’t seen much concern expressed on the theme of this tweet,

but with over 5 000 retweets (at time of writing), it certainly seems like some people are convinced, and possibly concerned. I’m however not inclined to think that the “10 year challenge” is a sinister ploy by Facebook to harvest this freely-volunteered data, in order to improve its facial recognition technology.

Anecdotes versus data in public discourse

“The plural of anecdote is not data” is a phrase well-loved by scientific sceptics. Often attributed to Dr Ben Goldacre, but probably originating with Raymond WoIfinger, the phrase cautions us against the mistake of thinking that what you experience – or what you and your granny or friends experience – might not actually be representative of any significant trend, or give you valuable evidence regarding the causal efficacy or role of something you might regard as significant.
