All of the graphs in this article were of 'childhood wakeup time.' AFAICT, it appears to be a graph of childhood IQ vs. adult wakeup time - unless, that is, the average child is going to bed around midnight, which seems wrong to me. In any case, though, I don't think these graphs have much to say about any true night-owls - if you're anything like me, you're not going to bed a few minutes after midnight, it's more like 6 AM, which would probably remove us from this data set altogether as outliers...
