People who jump to conclusions show other kinds of thinking errors
The article opens with a couple of examples of people allegedly not doing research:1. Most people make two trips or fewer to a dealership before buying a car2. when picking a doctor, many individuals use recommendations from friends and family rather than consulting other health care professionals or “formal sources” such as employers, articles or Web sitesAnd, of course, the last person I would look to for objective advice on buying a car is a car salesman!  Surely people have a good idea what they are going to buy, what they are prepared to spend and how they are expecting to finance it etc before going to a dealership for the car?Ditto too the doctor; if you are searching for a doctor, do you go and cold call other doctors for an opinion?  Or read the blurb on a website provided by or sponsored by the employer?  Its much more straightforward to ask people you know which doctors they recommend.Is the subtext of the starting examples meant to be saying that people should defer to car salesman and should ask doctors rather than friends and family to recommend other doctors?
