Well, you can certainly see the static thinkers and those who are dynamic thinkers.
A static thinker, in the context of thinking styles, is someone who tends to view the world in a fixed and unchanging way, lacking flexibility and adaptability in their thought processes. They often believe that abilities and intelligence are predetermined and unchangeable, and they may resist challenges or feedback. This contrasts with a dynamic thinker, who embraces change and sees potential for growth and improvement.
