2. Outsmarting requires modelling foreign cognition

Ordinary intelligence can operate through one’s own preferred reasoning-patterns.

Antaintelligence requires representing minds that reason differently:

different values;

different knowledge;

different biases;

different inference-styles;

different capabilities;

different models of oneself.

This develops cognitive model-plurality: the capacity to construct and operate through multiple possible cognitive architectures.

That is highly general-intelligence-relevant.
