Exactly. They influence but not in a good way.

Now that is a contradiction: You say "exactly" to then claim the exact opposite?

How do they interact? I said - and still say - those are completely independent statements.

How does 1) have any influence on 2)? If that individuals work is or isn't influenced by bonuses the general statement 2) changes somehow? Magically? Or vide versa, the same. No connection. No matter what you think of 2), the personal statement 1) is right or wrong independent of 2).

I think there is an implied "tend to" before "influence".
