Assessing dead people IQ is pseudoscience

A widespread phenomenon has hit us. We don’t know the IQ of a dead person (lots of time a genius) so we use stylometry.

And while there may be a correlation between, for example, the complexity of the written text and a living person’s IQ, the IQ tests are here to actually test people.

We may not know what the dead person’s IQ was because no one can know how he approached problems and so on. It is not an exact science, some people have really high IQs while not appearing so while some of them may have IQ lower and their text appears really complex.
