If you're the "being", and you're running a simulation of some system, you can absolutely create many parallel timestreams with different initial conditions. You can even return to some point in the simulation and try several intermediate conditions, resulting in different causal outcomes.
The many worlds interpretation would absolutely allow agency on the part of such a "being".
What if an unsupported claim is actually harmful to society, if believed?
15% of people believe the US government was responsible for the 9/11 attacks[1]. 42% of Britons believe that the UK sends £350M a week to the EU[2]. If voters make decisions based on such beliefs, I'd expect material damage to democracy.
Leave. Job-hopping is a pattern, not a single event. If I get a candidate with a good track record but one three-month stint, sure I'll query it, but "it wasn't a good fit for me" is a reasonable excuse and a good conversation starter if you can wrap it in a strong story for what _is_ a good fit.
Bait & switch jobs are a pattern, they happen all the time. Needing to leave several jobs in a row after only a few months at each place is just basic reality, normal circumstances for a lot of people given the way corporations treat employees now.
This assumes a single linear timestream.
