Assumptions of equality lead to poorer group decisions
"People of differing competence tend to give each other's views equal weight, preventing them from making the best group decisions, finds new UCL-led research.
This suggests that people with similar levels of competence make the best decision-making groups, as otherwise the tendency to assume equal competence can give undue weight to the opinions of less capable members.
The new study, published in Proceedings of the National Academy of Sciences, investigated how pairs of people with differing competence weighted their own judgements against each other's.

"People are incredibly bad at taking differences in competence into account when making group decisions," says senior author Dr Bahador Bahrami (UCL Institute of Cognitive Neuroscience). "Even when we showed them exactly how competent they each were, they still gave each other more or less equal say. Incredibly, this still continued when people were rewarded with real money for making correct decisions."
My interpretation: respecting religious delusions in politics and law results in bad political decisions and laws.
