Signpost 24

In a nutshell:

We should carefully evaluate ideas that challenge our beliefs rather than dismiss them outright. A strong emotional response to a new idea might signal a need to reconsider our assumptions. We should also avoid only accepting evidence that supports our existing views.

Key Chapters: 23

• 24.1 We should avoid adoption of ideas which we might have good reasons to avoid, but we should reconsider those which we discard for no other reason than that they question our beliefs. A good way to differentiate between these two is to examine the extent of the visceral reaction one has to the idea. p.83

• 24.2 Do not cherry-pick evidence that aligns with your believes while avoiding that which discredit them. p.83

• 24.3 A new idea makes you think that after all, your favourite notions may be wrong, your firmest beliefs ill-founded. p.83
