You can say ‘optimistic/pessimistic impact/effect’ but I would avoid it.

It can be used in very limited situations: (only one example)



1. Use ‘have’ as the verb. Stay safe – there are options (see below) but they have different meanings in different contexts.

2. I recommend using singular ‘have an impact’ rather than plural ‘have impacts’. Although both are correct, the singular version is the most common and ‘acceptable’.

There is something I don’t like about ‘impacts’ plural! I’ve checked and I know it exists but it sounds so much better in singular! Check what Ludwig says here:
