Expert writing Tips

Best practice

Use "have regressed" to describe a clear step backward from a previously better state. Ensure the context makes it clear what the previous state was and why the current situation is considered a regression.

Common error

Avoid using "have regressed" when describing a situation that has simply stagnated or remained unchanged. Regression specifically implies a movement backward, not a lack of progress.
