That's all and good, but let's go back to the original claim that was being discussed.
This. Communication beyond 2 SD less intelligent is near impossible outside of basic interaction.
If you define "basic interaction" as anything short of discussing economic concepts. Sure, it's impossible. But, to me at least, "basic interaction" means something you can manage with someone who barely even speaks your language.
Not being able to communicate with some 2 SD less intelligent would mean that someone with 129 IQ could manage better than basic interaction with someone with 100 IQ, but someone with 131 IQ would not be able to. Obviously a flawed premise. The decisive factor in the complexity of communication is the minimum of the two IQs, not the delta.
