The only way this could succeed is to accumulate a significant amount of data which showed an incontrovertible bias in age/gender/etc in the successful V unsuccessful candidates. How you would gather such data I don't know. For the OP to undertake such a process would mean he/she would be diverting their focus from attaining their goal, thus wasting valuable energy and time. It's not a practical option for them.
However it would be an interesting exercise and could throw a light on a PC can of worms.
You can be sure any such bias would be vigorously denied so your data would need to be rock solid.
