In the end, it comes down to trust. At some point readers/ listener has to take all the info and make that decision.
Personally I do trust info from WC folks- Garnett, Jeff C., Jeff. M, Spicer and lately Andrew Y. Not that I think they are perfect or without bias but I believe each one is professional enough to give their honest opinion.
Some of the newer people on the show (while enjoyable) simply haven't earned it yet.
