Opis

Experts, despite their importance and value, can be double-edged swords. They can make valuable contributions from their deep base of knowledge, but those contributions may also contain their own biases and pet theories. Therefore, selecting experts, eliciting their opinions and aggregating their opinions must be performed and handled carefully, with full recognition of the uncertainties inherent in those opinions.
