Those tests are pretty sensible to training effects, so giving them twice to the same person would result in a higher score the second time almost no matter what.
Good point, but the experiment could have a control group which doesn’t do anything but takes the tests twice.
And someone probably already did the control-group part of this experiment, i.e. measured how much does the IQ increase after test retake. So we just need to know if the measured IQ of the people who “clicked” increases more that that.
Also, as far as I remember, the effect is something like plus 5 or 10 IQ points. (May differ for different tests, though. Some tests have multiple variants, so even if you benefit from the training, at least you cannot benefit from remembering the correct answers in the previous test.) The people who “clicked” report that their intelligence increased tenfold or hundredfold—they obviously use a different scale, but if that corresponds to +5 or more IQ point, it should be measurable.
