The attitude that is NOT important in science is <u>b. having a closed mind.</u>
<h3>What is a closed mind?</h3>
A closed mind refers to a person who is not willing to consider different ideas or opinions.
A closed mind cannot engage in scientific inquiries.
Scientific inquiry helps scientists to study the natural world in diverse ways before proposing explanations based on the evidence derived from their scientific activities.
Thus, important attitudes in science include:
- Curiosity
- Creativity
- Skepticism.
- Honesty
- Flexibility
- Persistence
- Open-mindedness
- Tolerance of uncertainty
- Acceptance of the provisional nature of scientific explanation.
But, having a closed mind cannot help in science.
