I would allocate to whatever seemed to me like the most likely to be fruitful.
On what basis do you determine which theory is going to be more fruitful?

Why would I think it was a good idea if there was no positive evidence and 'perhaps' even contradicting evidence? It doesn't make sense to me.

It is clear therefore that subjective opinion is not based on external facts. So it is perfectly valid to subjectively like a theory despite contradicting scientific evidence.

The hypothetical example I gave you asks you to choose between allocating funds on a subjective basis as opposed to adopting a more objective perpective. Hopefully the question makes more sense now?
