It’s not like there’s a shortage of scientific facts out there spelling it all out for us.
But let’s be honest — not many people can relate to scientists sharing their data, no matter how compelling it is.
When I give talks as a scientist versus when I’m talking to a friend, I don’t think I’m any more persuasive. In fact, I think as a scientist, I may be actually less trusted.
I guess here he's saying like "I'm not very persuasive", but I'm not familiar with this usage (I'm only used to expressions like "I don't do that any more.") and don't exactly know what this sentence means.
Does "I don't think I'm any more [adjective]" mean "I'm not [adjective]"?
