Google released a bunch of icons for free as part of their Material Design project. I amused myself recently by considering how we might use some of them to symbolize different kinds of common thinking patterns. These are what I came up with:
Missing the point:
Circular thinking:
Dwelling in the past:
Over-focusing:
Thinking outside the box:
Uncertainty:
Skepticism:
Wanting a hug:
Over-complication:
Self-contradiction:
Narcissism:
Negative thinking:
Defensiveness:
Drunk:
Suicidal:
