If you name a group, I can give you a mathematical model that will unfairly discriminate against that group, purely through how I divide up the population. "Math" is a mechanism, not an indicator of right or wrong.
Actuarial Science is also a mechanism, not something that indicates right or wrong. It gives you answers to questions. But questions themselves can be biased.
There is no desire to "show" anything beyond having an accurate representation of probability.
