Abstract Thinking and Rising IQ Scores

IQ is rising in many parts of the world. What's behind the change and does it really mean people are cleverer than their grandparents?

It is not unusual for parents to comment that their children are brainier than they are. In doing so, they hide a boastful remark about their offspring behind a self-deprecating one about themselves. But a new study, published in the journal Intelligence, provides fresh evidence that in many cases this may actually be true.

The researchers - Peera Wongupparaj, Veena Kumari and Robin Morris at Kings College London - did not themselves ask anyone to sit an IQ test, but they analysed data from 405 previous studies. Altogether, they harvested IQ test data from more than 200,000 participants, captured over 64 years and from 48 countries.

    Shh! Don't tell people that. What people say about IQ tests can give you insight as to what their IQ is likely to be.

    People that have not figured out that half the people are dumber than the median give themselves away as being on the wrong side of it! Exceptionally high IQ is given away by statements about IQ tests being not very relevant but better than nothing and mumbling something about r values and correlation.

    Uhh, that's not how the median works. Which side does that make me?

      You are thinking of mode, or possibly mean, median separates half the sample set from the other half of the sample set. That means humans. I'm sure you know what side you and the moderators that +4 your post are on. Here is an audience appropriate explanation. [mathgoodies.com]

        My apologies. You're absolutely right. That'll learn me to try and apply statistics knowledge that hasn't been used in anger in years. Use it or lose it.
