We all know how inadequate they are. Correlations with real world variables rarely run over 25% of the variance. What is amazing is that they have lasted so long. The reason why: intelligence has never been defined in such a way that everybody jumps on the bandwagon and says Yes, that's it; that's what real intelligence is. And the reason for that is that like the 12 blind men and the elephant, everybody is looking at a different set of variables with every intellectual task they explore.</span><br></div><div class="gmail_default" style="font-family:arial,helvetica,sans-serif;font-size:small;color:rgb(0,0,0)"><span style="color:rgb(34,34,34);font-family:arial,sans-serif;font-size:12.8px"><br></span></div><div class="gmail_default" style="font-family:arial,helvetica,sans-serif;font-size:small;color:rgb(0,0,0)"><span style="color:rgb(34,34,34);font-family:arial,sans-serif;font-size:12.8px">Individually given IQ tests are the best we have because they do correlate with more other variables than any other sort of test.

An IQ test takes a lot for granted - ability to walk, hold a pencil, fill out the test as a mechanical challenge, find the person you need to hand it to, etc. As a result, Raven's matrices are not a very good measure of the intelligence of disembodied fragments of neural networks that are now the subject of deep learning research projects. Such fragments replicate some small areas of a human mind but they do not form an integrated whole capable of functioning in the real world, and their ability to perform some elements of an IQ test is not predictive of real world performance. </div><div><br></div><div>Our fascination with IQ testing stems from the test's ability to predict real-world function, including the eternally important who-whom question, and not just silly puzzle solving. Deep learning network IQ testing is therefore for now less interesting but once the separate deep learning modules become integrated into human-like systems with real-world performance, their IQ will be acutely interesting in the who-whom context.</div><div><br></div><div>This said, it is amazing that tiny deep learning neural networks with mere billions of parameters manage to equal the performance of middling-sized chunks of brain (e.g. the subcortical and cortical visual processing centers).</div><div><br></div><div>Rafał</div></div>
