I am not following that statement, please clarify.

so basically of course youll see differences within a common population, some white people with higher and some white people with lower iq

Ah, in that sense.

its a bellcurve

but some bellcurves are tighter or higher up on average

like men have larger bellcurves than women in iq

with more people on the extremes

an example

I fail to see why this should matter in a political sense though.

It affects polices and casual relationship with the information the supports policy

if you believe all human are equal in intelligence than it makes sense that if you see any particular group fall behind, it must be due external factors

I hold no such believe.

in comparison, if you understand the opposite to be true, than you wont hold that position

But again: one way or another I fail to see how that matters politically.

more so a hypothetical

does political policies matter?

like affirmative action or positive action?

I mean, policy itself is inherently consequential.

or wealth redistribution policies

What?

But this isn't even about policy, this is merely a scientific point.

policy is very consequential, it affects our quality of life

policy is based on information

Policy is mostly based on desire.

that information can be analyzed in a scientific matter

and proven wrong or right

Science can merely inform you in regard to how reality functions.

You can consider scientific facts in regard to setting policy, but the policy is merely set to reach a desired outcome, regardless of the scientific fact per se.

and how you think reality operates affects your desires

I do not contest that. Not entirely at least.

like the desire to stop climate change is based on research that shows climate change is problematic

Err...

You are making a slip there.

or that climate change is real

no im not

Climate change is real, yeah.

But it being problematic is a moral judgement.

And inherently human.

and its problematic to agriculture, energy production and so on

And really a judgment tying in with desire.
