He asked for the "strongest indicator" of IQ. An effect of at least around 7 IQ points doesn't fit that.

Technically I believe the strongest indicator is the IQ of the mother, which is interesting and you can dig deeper into that. However, keep in mind that I said an early education program affected IQ by roughly that amount. It also seems to be affected by how much one attends school and the quality of the school. So education in general would be a different story.
