‣ In biological evolution, the process of distilling knowledge (encoded in the DNA) is error-correcting (through natural selection). It went extremely far (evolved into humans).
‣ Deference to expertise might be still slippery. Experts cannot ultimately escape the push towards margins in their expert judgement based on incomplete understanding or data. From within an organisation, it might be impossible to transcend the routine and political stuff and notice an emerging problem. What we don't believe we cannot see. Thus, relying on human rationality is unreasonable.
