What you should avoid for creativity are

• Confirmation biases
• A confirmation bias is the tendency to search for evidence that confirms our beliefs rather than to search for evidence that falsifies those beliefs.

• Surveillance
• Being watchedExpected evaluation
• Especially when this leads to over focusing on how work is going to be evaluated

• Extrinsic motivators
• ..and lack of intrinsic motivation

• Competition with peers

• Constrained choice
• Too many limits on how to do the work.

People tend to verify what they believe.
You should avoid confirmation biases for creativity.
And also, you should test your programs, avoiding confirmation biases.
