Playing totally unmodded with all DLC active except Penumbra and all add-ons active except for the Pug hero; verified game files before game started to be sure.  Infallible Authority is not giving the per hero level aspect of the FIDSI bonuses promised, and doesn't seem to be giving flat bonuses on the system the hero is assigned, either.

Here are the bonuses on my capital system:

Pop 10 times 0.5 = 5, but where's the hero level modifier?  The hero on the planet is level 20 so that should be +100, not +5:

For alternate reference, here is the planet where the Hero with the senator skill is stationed:

The +40 FIDSI seems wrong to me, and I noticed the same flat bonus on my home system for the same number of pops.  No Behemoths involved in either system.

Yeah, you're right Skummeh, I asked about it to the patch team, seems they forgot to add the "per hero level" effect multiplier to the skill.

The skill is a third ring level skill. You get the senator skill as soon as level 10, so starts with 5 FIDSI per pop, as soon as you get access to it. I'm all in for skills that are better than others, but this one blows out of the water almost any other third and fourth ring senator skills.

Yeah, maybe 0.2 would be a very good value, still plenty strong. I will fix it on Community Fixes, no balance changes though. Not a big deal.
