People's judgement can get biased, even clouded, by financial interests.
It can also get biased or clouded by ideology, political affiliation, emotional state, what their friend tells them, etc. There is nothing particularly special about financial interest.
If someone was to sit in judgment over the issue, and be the person who decides the issue, you would obviously want to exclude people with a financial interest (at least any significant interest) with one side or the other.
But we aren't talking about selecting the decision makers, but rather presenting arguments. The logic of an argument stands by itself. If a stupid, foolish, biased person, with a large financial interest in one side of the case, makes a valid argument, its still valid. If a smart, wise, impartial person makes an invalid argument, its still invalid. |
