The statement "All of the following may interfere with problem-solving except" implies that one option does not interfere with problem-solving. Out of the given options, the one that does not interfere with problem-solving is "correctly using an algorithm when appropriate." Therefore, the correct answer is "correctly using an algorithm when appropriate."

To determine which option may interfere with problem solving, we need to understand the meaning of each choice. Let's break it down:

1. Functional fixedness: This is a cognitive bias that limits a person's ability to see objects or concepts beyond their typical or intended function. For example, if someone struggles to think of alternative uses for a common object, it may hinder problem-solving abilities.

2. Not knowing enough information: Having insufficient knowledge or data about a problem can make it challenging to come up with an effective solution. Lack of information may lead to faulty assumptions or inability to identify the problem's root cause.

3. Using a heuristic: A heuristic is a mental shortcut or rule-of-thumb that simplifies problem-solving by providing a quick solution without an exhaustive analysis. Sometimes, heuristics can be helpful, but they may also influence biases or lead to errors.

4. Correctly using an algorithm when appropriate: An algorithm is a step-by-step process that guarantees a solution when followed correctly. If a person has the appropriate algorithm to solve a problem but fails to apply it correctly, it may hinder their problem-solving efforts.

5. The mental set: Mental set refers to a tendency to approach a problem in a specific way based on past experiences or preconceived notions. This can create a "set" state of mind that may hinder finding alternative solutions.

From the given options, "correctly using an algorithm when appropriate" does not interfere with problem solving. Algorithms are predefined, systematic procedures designed to solve specific types of problems. If employed correctly when applicable, algorithms can facilitate problem solving.

Therefore, the correct answer is: correctly using an algorithm when appropriate.
