if you wanna give dummy policy, you should use this code

player:SetNumFreePolicies(1)
player:SetNumFreePolicies(0)

ex)
if player:GetCivilizationType() == dollCiv then
if not player:HasPolicy(dollPolicy) then
player:SetNumFreePolicies(1)
player:SetNumFreePolicies(0)
player:SetHasPolicy(dollPolicy, true)
--print("Set to DOLL")
end
else
if not player:HasPolicy(nonDollPolicy) then
player:SetNumFreePolicies(1)
player:SetNumFreePolicies(0)
player:SetHasPolicy(nonDollPolicy, true)
--print("Set to NONDOLL")
end
end

Is there a specific reason to use this method? Through my tests, just using the player.SetHasPolicy method would give that player the policy. It seems redundant to set the free policies to 1 then to 0 when we grant the policy, especially when we still grant them the policy when free policies = 0.

originally quick speed first policy cost is 15
but if this code doesn't exist, first policy cost will increase to 20

That's interesting how SetHasPolicy also adds one to the number of total policies, it has been fixed. Thanks!
