Bandwagon fallacy   a  -- b  raising concern about competing products that might be tarnished
Argument of antiquity     -- c  don't need good information because of the source
All natural     -- d  must be true because people have believed it for a long time
From authority     -- e arguing against the person rather than the argument 
Quantum physics argument     --  f throw out terms that sound learned and over your head to make the other person think you know more than you do
