Presumably there's more to this than comes across in your comment.

After all, you don't avoid the unconscious bias of a single mind by adding more minds. That just gives you three sets of unconscious bias and adds biases caused by group dynamics.

Do you have a link? I may be googling the wrong terms.

You can still avoid most of the effects of a worst-case bias by adding two additional measurements.

Rather than 1 person, 30 minutes (one measurement), given 3 who all had the same experience, you are less likely to have all three have an impression unconnected with the substance of the conversation.

You're right that it's an advantage, but it reduces noise, not bias.

Bias by definition skews systemically in the same direction so the positive effect of taking multiple measurements is minimal.
