How unreasonable expectations for estimation set your people up for failure

Consciously we know that everyone, every single human on this planet, suffers from cognitive biases.

This article is written for people who are stakeholders in any sort of project but the fact is I hope it can be useful for anyone, especially Product Owners or Scrum Masters to use when working with stake holders to help manage unreasonable expectations when they come. And they always come.
