Independent Evaluation

Forming your own judgement before hearing what everyone else thinks.

What it means

Independent evaluation is the practice of forming your own assessment of something before exposing yourself to other people's opinions. It sounds simple, but it runs against some of our deepest social instincts. We're wired to look to others for cues about what to think and how to react - and in the age of instant reviews, ratings, and comment sections, other people's opinions usually reach us before we've had a chance to form our own.

The problem with hearing others' views first is that they become anchors. Once you know that a film has a 95% rating, or that your boss thinks a proposal is weak, it's almost impossible to evaluate it without that information colouring your judgement. Your "independent" opinion becomes a slightly adjusted version of someone else's.

This matters most in situations where diverse perspectives are valuable: team decisions, creative work, hiring, investment. If everyone reads the room before speaking, you don't get five independent opinions - you get one opinion five times. Independent evaluation protects the diversity of thought that good decisions depend on.

In the real world

A team is evaluating a new product idea. The most senior person in the room speaks first and says they love it. Watch what happens next: the rest of the team's "independent" assessments will skew heavily positive. Not because they're sycophants, but because the anchor has been set. If instead everyone wrote down their assessment before anyone spoke, you'd get genuinely independent evaluations - and probably a much more useful conversation.

The thought to hold onto

Your opinion is most valuable before it's been contaminated by someone else's. Form it first, share it second.
