Final answer:
One barrier to innovative problem solving is persisting in using past successful techniques, known as 'mental set'. It prevents considering new information which is vital for creativity and effective problem-solving. Overcoming this requires divergent thinking and open-mindedness.
Step-by-step explanation:
One barrier to innovative problem solving is persisting in using techniques that have been successful in the past, also known as mental set. This relates to a fixed pattern of thinking that fails to consider new information or perspectives, thus hindering creativity and problem-solving abilities. Innovative problem solving often requires divergent thinking, which is the ability to think "outside the box" and come up with multiple solutions to a problem. Conversely, a mental set involves a rigid approach and tends to repeat past strategies even when they are not currently effective.
Understanding and recognizing this barrier can encourage more adaptive and creative approaches to problem solving, such as collaboration, expanding one's knowledge, and engaging in divergent thinking. It is essential to overcome this barrier to embrace new and innovative solutions, particularly in areas where constant innovation is necessary, such as technology, medicine, or engineering.
