What a complex issue. In part I am glad that the intelligence genes are proving elusive. I fear not the short term but the possible long term results in a society with decreasing resource distribution and increasing governmental control.

On the other hand, if an IQ test could get me a job (or allow me to keep it) rather than nepotism, I would welcome it.

do we really think we can pinpoint one specific set of genes which control such an abstract feature of possibly one of the most complex organs in the human body?

i would think that every gene coding for a protein found in the human brain effects one's intelligence.

"Intelligence is just a tool to be used towards a goal, but goals are not chosen intelligently." -- Larry Niven

I think we look for computer augmentation to drive up intelligence before tinkering with genes produces results in that department. And it will be like anything else in the realm of technology -- those who refuse it will soon exist only by the sufferance of those who do. I wonder what folks with intelligence so far beyond modern folks would or will do with it?

They are going in the wrong direction. They should be working out the rules for how genes interact with each other to build an organism, then work out how to model those interactions in various stages.

The way they are going about it is kind of like dragging a fork around the inside of a computer and watching the screen for changes, and then trying to guess what does what.
