The consumers directly don't. But as a consumer I don't know how to evaluate an automobile, a smart-phone, or other products. But there is a market that provides the relevant data to consumers. Before I buy a car, I check out USNews, or Edmunds; before I buy any product I check out the relevant resources. Because of the way the FDA is structured, not much non-FDA research and reviews are being done. Lol. I didn't propose a solution.
