A working paper from the Massachusetts Institute of Technology and Stanford collected the money questions of 952 real people, then simulated a lifetime of following the artificial intelligence (AI) advice those questions produced. The prompts written by women resulted in $59,890 (about £44,000) less wealth by age 60 than those written by men. Both groups faced identical simulated circumstances, so the gap came from the questions themselves and from how the model read them.
The figure is a simulation, not a record of what happened to anybody. The authors measured the result of acting on the advice, 'not the effect of receiving advice.'
