No.
False beliefs are not necessarily evidence of psychosis. I'll go out on a limb and assert that most false beliefs are not so. The *reasons* for holding beliefs are indicative of psychosis and not the beliefs themselves.
If, for example, I believe that my partner is cheating on me, and she is not, in most cases, I am merely wrong. If I believe that she's cheating on me because a time-traveling slug from the Andromeda galaxy told me so, that would be psychosis.
Likewise, if I believe that my partner is cheating on me, and she is, but I came by that information based on my belief that a time-traveling slug from Andromeda told me so and no other reason, then that belief is rooted in psychosis.
