I can't give an error for a mental error.
I'd say, failing to move is a physical error.
In comments after Rule 10.12(a)(1) (baseball)says “…It is not necessary that the fielder touch the ball to be charged with an error. … For example, the official scorer shall charge an infielder with an error when a ground ball passes to either side of such infielder if, in the official scorer’s judgement, a fielder at that position making ordinary effort would have fielded such ground ball and retired a runner.”
So, in your judgement, if the 2nd baseman should have fielded the ball with ordinary effort, an error could be charged.
