I can only say that humans do lazy evaluation.

humans do not calculate the exact value of positional factors when they see that
they lose a queen.

If I understand correctly suppose
Diep calculates 1.e4 e5 2.Nf3 Qh4 3.Nxh4 and calls evaluation

It does not say that it is not good based on lazy evaluation but prefers to call
an expensive evaluation to find the exact value of the position.
