Using 'reaction' and 'response' interchangeably without considering scope. 'Reaction' is often immediate and instinctive, while 'response' can be more considered.

'Reaction' often implies an immediate, instinctive, or emotional response to a stimulus, sometimes without conscious thought. 'Response' is a broader term for any answer or reaction, which can be more considered, thoughtful, or delayed. Reaction is often quicker and less deliberate than response.

Assuming 'reaction' is always negative. Reactions can be positive, neutral, or negative depending on the context.

While 'reaction' is sometimes associated with negative or adverse responses, reactions can be positive, neutral, or negative depending on the stimulus and context. Avoid assuming reactions are inherently negative; consider the full range of possible reactions. Reactions are valenced based on context, not inherently negative.
