It is debatable whether creativity and mental illness are absolutely unrelated. Some studies have shown a potential link between certain mental disorders, such as bipolar disorder and schizophrenia, and creativity. However, it is important to remember that creativity is a complex phenomenon that can be influenced by various factors, including personality traits, upbringing, and environmental factors.

Intelligence and creativity are related but not the same. While intelligence involves the ability to problem solve and reason logically, creativity involves thinking outside the box and coming up with novel ideas. It is possible for someone to be highly intelligent but not particularly creative, and vice versa. However, there is evidence to suggest that individuals with higher intelligence may be more likely to exhibit creative thinking.

Creativity is not beyond scientific investigation. While the creative process may be difficult to fully understand and quantify, researchers have made significant progress in studying creativity through various methods, including neuroscientific studies and psychological experiments.

Creativity plays a crucial role in adaptation to the environment by allowing individuals to come up with innovative solutions to challenges and problems. It enables individuals to think flexibly and creatively in response to changing circumstances, ultimately leading to better adaptation and success.

The social significance of originality and individualism lies in their potential to challenge societal norms and spark change. While originality and individualism can be beneficial for innovation and progress, they can also lead to conflict with authority and disrupt social order. Balancing creativity with the need for conformity and stability is essential for a functioning society.

I agree that creativity requires both originality and effectiveness. In this context, "effectiveness" refers to the practicality and usefulness of a creative idea or solution. Creativity is not just about coming up with novel ideas, but also about implementing them in a way that has a positive impact.

I agree with Bruner's definition that creativity requires "effective surprise". Creativity involves generating ideas or solutions that are not only surprising and unexpected but also effective in addressing a certain problem or challenge. The element of surprise adds a sense of novelty and innovation to creative endeavors.

Ideas that can be seen as "good and relevant" in the context of creativity are those that are not only novel and original but also have practical value and relevance to the given task or problem. Creativity involves producing ideas that are not only new and creative but also meaningful and applicable to the situation at hand.
