collective myopia 

the post-debate discourse implies that those close to biden couldn't have possibly expected that the outcome of the debate would be the party and the base's cry for candidate swap. yet they somehow initiated a debate 2 months ahead of the debate schedule. 

as individuals we do ok with theory of mind but as groups we have such a hard time thinking the outcome might've been expected to those that could have influenced it prior to it happening.

Translation for this channel:

The strategists were aware that Biden was likely to lose and realized they needed to replace him to have a real shot at victory.
Directly swapping him out wasn’t feasible, either because he was reluctant to step down or because it would disorient the voter base.
They orchestrated a debate two months early to provoke public outcry and pave the way for his replacement.
