Mitigating Disadvantages w/o Self Control Number

[Captain Joy]

Are there any tried and true methods of mitigating Disadvantages that don't have a Self Control number?

I welcome attempts to sell me appropriate GURPS titles. E.g. it won't surprise me a bit if something in the Power Ups line addresses this.

This came up because I want my to Star Trek Andorians to be paranoid, and the stock Paranoid disadvantage seem to qualitatively fit the bill; but as written, the Disadvantage is just too debilitating. Something like adding a Self Control number might be all it needs, but I'm wanting to make sure I price it fairly and avoid unintended consequences.

EDIT: If you want to see my current solution, jump to post #11.

In situations like this I use the % chance of resistance against the given self control number as a benchmark. For example, 12 gives a 75% chance of resistance, 9 gives a 37.5% chance, etc. Though paranoia is a hard thing to quantify in percentages.

Self-control rolls are against 6, 9, 12, and 15. We can extend this sequence to cover the range 0-3-6-9-12-15-18-21 with each step costing 50% of the base cost. Hence, rolling against a self-control number of 18 is worth 0 points, while the guaranteed failure of rolling less than 0 is worth x3 the usual cost.

If a disadvantage applies all the time, you might then assume that it has a self-control number of 0, and an effective triple cost. If it gave 30 points, giving it a self-control number of 12 would reduce it's value to 10 points.

I see nothing wrong with adding Self-Control ratings to most other mental, not-self-imposed disads that lack it, like Paranoid and Callous. (For the purposes of this, however, I wouldn't allow it on Pacifism.)

This is wisdom. There are a small host of mental and social disads that would go fine with a Self-Control mitigator.

And quite a few that don't, hence why I specified "not self-imposed". Quite a few mental disads are self-imposed, which adding a Self-Control Rating to would act kinda weird.

While the standard self control roll might not be the right solution, I could well imagine someone say have a code of honor that they adhere to almost always but do slip from it time to time.

A self control type mechanic and lower price might make sense for such.
