Do IQ test results mean anything at all?

The answer is yes — but only in certain circumstances and that "yes" comes with a whole bunch of caveats. At Discover, Emily Sohn has a nice basic primer on what we know now about intelligence testing and what your score on an IQ test does and doesn't mean.

    High IQ's run in my family, and that doesn't guarantee anything. We cover the full spectrum from success to failure, and I've spent a lifetime taking orders from people who needed even the simplest things explained to them almost daily, but were convinced that they were the smartest ones in the room.

    Me go now.

    No problem. Just raise some of them in a sensory deprived environment. For example, if 75% of them have an IQ of 100 and 25% have an IQ of 50 that'll give an average IQ of 87.5 with only 25% below it. There are, however, some ethical problems with doing this.

  5. Sensory deprivation is cruel, plus it isn't very efficient. Surely just assigning children we don't like much a regimen of lead supplementation would achieve the same effect, while still allowing them to live in a natural environment?
