Take the time to consider the biases of the people from whom you get advice. Likely you already know a lot of which biases affect them significantly and may be able to guess what more of them are. Everyone has different biases and all people react to them differently. What is a strong bias for one person is a weak one for someone else. Consider talking to your consultants about their biases, they should be open to this conversation (and if not, be extra cautious) and hopefully have thought about it themselves, even if not in depth or in the same terms.
