There are two main reasons why we sometimes ignore advice:
-We ignore advice when we think the person giving the advice is wrong (though it might actually be us that’s wrong).
-And we ignore advice because we sometimes want reality to be different from what it actually is (which sometimes influences the above reason).
Even when we think the advice is probably accurate we might still ignore it, because we have a need for autonomy. We’re sometimes defiant even when it’s in our best interest not to be, to the point that we sometimes seek out confrontations and power struggles.
When we know what our motives are we can make better assessments.
