Adjective
untrapped (not comparable)
Not trapped.
You have to get a little untrapped from too much prior knowledge. Norman Foster Ramsey, Jr.
The untrapped mind is open enough to see many possibilities, humble enough to learn from anyone and anything, forbearing enough to forgive all, perceptive enough to see things as they really are, and reasonable enough to judge their true value. Matsushita Konosuke
