Friday the 13th study

Apparently, Friday the 13th is not unlucky, according to Dutch researchers: link to article.

I would like to see a parallel psychological study, to see if people are more careful on Friday the 13th, go out less, drive less (or just shorter distances) – and if people considering criminal activity hold off until the next day. I also wonder if there is an upswing in the types of “bad luck” they chose to survey on Saturday the 14th…

    I'm wondering if there is other motivation for this kind of study besides "my boss asked to"… It seems one more way to waste money!

    In France, Friday the 13th is considered a lucky day. There is even a special draw of the national lottery when it occurs.

    Monday the 13th, on the other hand, is very bad

    It wasn't too lucky for the Knights Templar Oct 13, 1307.

    For those of you who do not suffer from paraskavedekatriaphobia, here is an interesting statistic about that unlikely day: the 13th is more likely to fall on a Friday than any other day…

  5. datacharmer says:

    Apart from avoiding risky behaviour on Friday the 13th because it is deemed unlucky (which might well be happening), you should also consider that Friday the 13th – unlike other Fridays – CAN'T be Christmas or New Year's (where people get drunk and drive), and it will also be associated with a lower (or higher) probability of falling before a bank holiday weekend (or I guess in the States Independence day, etc).

    I guess all I'm saying that it could well be other factors driving this result other than a change in people's behaviour because Friday the 13th is 'unlucky'.

    How about accidents on Friday the 12th of Friday the 14th? The article only compares Friday the 13th with an average Friday – in fact, it doesn't even reveal whether the 13th is least accident prone Friday in the book…
