Not really,.. because I'm only saying 80% for the sake of arguement...
I base it on no evidence... other than the fact that 97% is a high percentage.
The facts say, 97%... wrong or right, it is the number stated by others that know more than you or I...
My compromise of the figure does nothing to the facts...
My point is,.. is it more reasonable to believe a 20% minority opinion than a 3% minority, in a field of expertise in which none of us are at all knowledgeable?...
I'm just assuming that experts know more than us...
...and that's a very safe assumption...

...
Science also says that there are at least 10 dimensions...
I can't even grasp the idea of it,.. but, I will assume that they can...
Because they are in some consensus on this...
I also can't figure out how excited particles can run down a wire and make my toaster work,.. but they do...
Some things you just have to believe, even if you don't understand them, because wiser men than you agree... and the evidence supports them...
I believe the globe is warming because those that study it, say so...
I don't believe these people are as motivated to lie as their detractors...
The money points the other way...
The same as "Tobacco science" did a few decades ago...
