Once you have made a decision about an applicant for some reason (such as the way they filled out the application blank or something you like or don’t like about their resume or appearance or the way they sounded on the phone, etc.), it is almost impossible to remove that feeling or judgment from the equation — be it good or bad.

No matter the evidence that piles up on the other side, you’ll stick to that gut feel, judgment call because you’re not simply trying to change a decision you made, you’re asking yourself to admit you were wrong.

No one likes to admit (even to ourselves) that we’ve made a mistake. In fact, we often work hard to prove ourselves right.

The only way to overcome this bias is to admit you may not have all of the information necessary to make a good decision and try to reevaluate your thinking from a new perspective.

If you find yourself liking an applicant, ask him or her tougher interview questions to prove yourself wrong.

If you find yourself not liking a candidate, try asking this person easier questions and give them a chance to prove you wrong.
