Creativity and divergence are not enough to initiate innovation—people's behaviour needs to change, and they also need to trust their colleagues.
Innovators who have changed the world with their inventions exhibit high motivation, non-conformity and are comfortable with ambiguity.
'Riding the Monster: Five ways to innovate inside bureaucracies' by Eric Haseltine PhD, Chris Gilbert MD PhD argues that these traits are insufficient. The reason is that innovation requires people to change deeply ingrained behaviours and foster loose, informal social networks.

This allowed people who would generally resist change to relax, form friendships, and accept change.
In these settings, people don't fear embarrassment at advancing new ideas or trying novel approaches. On the contrary, they are prepared to risk the change if they have established trust. Thus, the psychology of innovation is summed up by what Gilbert calls the innovation equation:
