Key Details

Sometimes yes, sometimes no.

The problem starts when I challenge that answer with something as simple as: "Are you sure?" Very often, it suddenly changes its conclusion and explains why the opposite answer is actually the correct one.

Then I ask again: "Are you sure?" Or: "You're very easy to convince." And it can flip back again.
