For years you have believed that eating kumquats is really good for your health. You drink kumquat juice and buy the highest-premium kumquat bars, and you've run a pro-kumquat website for years.
 
  Now you learn that a major review of 18 studies has found that kumquats have no benefits and are even potentially harmful. What would be the most constructive way for you to reduce your dissonance caused by this discovery?
  a. The research is biased. I'll wait for a more scientific study.
  b. I must be an incredibly stupid person to have been eating kumquats all these years.
  c. I thought I was doing the right thing, but I'm glad to have better information.
  d. I'm furious and going to start an anti-kumquat blog immediately.
