Anchoring biases, group think and other nuisances… John Clapham
Agile methods encourage creativity through collaboration - but those ideas, and our responses to others, are filtered through our own perceptions. Most worrisome are the kind of perceptions that we've unknowingly built up and curated over many years, until we are barely aware of them.Working in groups can improve things, and we've learnt to value the wisdom of crowds. But groupthink creeps in with alarming ease, depriving the team of diversity and breadth of experience.

Parallel Thinking“Parallel thinking: each thinker puts forward his or her thoughts in parallel with the thoughts of others.“
Why ‘put on’ a hat?- Maximise sensitivity - allows us to think of one
thing at a time.- Practice unfamiliar modes of thinking.- Ritual engages specific thinking modes.
“Stop being such a pessimist”vs
“Black hat thinking is later”
Stop being yourself!
“We’ll have timefor those thoughts
later”
Green Hat- The creative hat- New Ideas and alternative concepts- Identify a void, the need for an idea.
Red Hat- Emotions and feelings- Intuition, perception- Don’t need to justify, it’s your own emotions.
