Yikes. These data jerked me right back to the first lab of my genetics course, where we learn basic principles of probability with exercises in coin flipping and dice rolling.

More Americans incorrectly say that the likelihood of flipping two coins and getting two heads is 50% than correctly say it’s 25%
I never even thought to ask them if they had a different, incorrect assumption about probability, we just did ‘experiments’ to see what the results were (and also learned some simple statistics and calculations). I am confident that if my students were asked this question they’d say 25% with no hesitation…although they might also go on a bit about chance variation and bell curve distributions.
Although the ignorance on display in that chart might explain a different phenomenon: US gambling addiction is ‘out of control’ as betting markets boom, policy expert warns. Yeah. I swear that almost half the ads I see online are about betting.
Prediction market platforms – where users can bet on everything fromaward winners and war developments, to what someone might wear, or what an artist will sing on stage – have meanwhile surged in popularity in the last few years, with more than $1bn traded on Kalshi during Super Bowl Sunday alone.
Prediction market platforms contend that they are not gambling platforms, but rather financial trading platforms. Critics argue they are gambling under another name.
It’s gambling.
It’s preying on stupid people. That chart says that that’s about 48% of the US adult population, so I can see how it’s lucrative.
Wait. I just noticed the footnote on the chart: “Responses of ‘0%’, ‘75%’, ‘100%’, and ‘something else’ are not shown”. I assume that’s the difference between the frequency of responses shown and 100%, but I want to know how deep the ignorance runs.
