We’re all familiar with the Biblical word about not judging others. But a new report says we may not be able to control making instant judgments about people we meet.

According to a new study published in the Journal of Neuroscience, the brain immediately determines how trustworthy a face is before it’s fully perceived, which supports the fact that we make very fast judgments about people The researchers displayed a 30-milliisecond glance of faces with qualities designed to project how trustworthy someone is, and the brains of the people in the study all had the same response even though they didn’t even realize they had seen it.

Now, the command in the Bible about not judging people is still valid and actually is not talking about these kind of auto response instant judgments anyway.

But at first glance, this study could give some people an excuse for how they treat someone. Kind of a “hey, it’s not my fault, it’s just in my genes” kind of thing.

Except that when it comes to making judgments about others, what’s in our brain is not important as what’s in our heart.
