Think before generating output - plan the entire sentence before you generate the first word(s) and maybe talk yourself into a corner. Tree-of-Thoughts (not Chain) is one way to provide something a bit similar - kind of like DeepBlue or AlphaGo generating possible branching future lines of play and picking the one with best outcomes.

To be more brain-like you'd really want the system to generally be "looping" internally - a bit like our thalamo-cortical loop - and only start outputting when the thought had gelled.

Also the parameters are optimized also with loss of future tokens in the sequence.
