Neuroscience Twin study suggests rationality and intelligence share the same genetic roots - the study suggests that being irrational, or making illogical choices, might simply be another way of measuring lower intelligence.

These sort of tests are so skewed to experience

Take the ball and the bat where together they cost 1.10 ... If you are used to puzzles like this it's simple but if you aren't it's much harder. But you might be more familiar with other sort of logical tests that if they had used the type of puzzle you were used to you would do better

They aren't good predictions of real world success they just measure how familiar you are at that particular sort of puzzle

People have given very basic counters to IQ tests such as you gave just now for as long as they've existed. But these counters just largely aren't true. 

Yes, education and practice have an effect, but most of the weight is genetic.

It is also untrue that these aren't good predictors of real world success. Intelligence is the best predictor according to most studies, although conscientiousness is up there as well.

Im just going off my interviewing and best practices at a high level in finance. These puzzles just aren't really used at all for anything but the most entry level

Predictors of future success tend to be more complex and nuanced than brain teasers which are horrendously hit and miss.

The people that rely on them tend to be a a bit basic, lazy even.
