For the fun of debunking,
duty of skepticism,
and love of science.

It is difficult to say what truth is, but sometimes it is so easy to recognize a falsehood.
--Albert Einstein

The trouble with the world is not that people know too little, but that they know so many things that ain't so.
--Mark Twain (Samuel Clemens), Will Rogers (William Penn Adair), or Josh Billings (Henry Wheeler Shaw)0

When you read or overhear nonsense or the besmirching of science, do you have an urge to respond and set things straight? Are you seeking knowledge and tools to help refute such foolishness? Would you like to be the bane of forums and blogs with topics about pseudoscience, bizarre conspiracies, quackery, or the supernatural? If yes to any of the above, then you have come to the right place. Welcome!

Debunking can be an easy sport and it can require tedious research to learn a subject and get your facts straight. Although ideologues and true believers cannot be swayed by logical arguments and credible evidence, there might be others on the sidelines who can be influenced.

True believers can be quite deluded. You say one thing and they will hear another (see Illusion of Superiority for an explanation). And in the case of bizarre conspiracy believers, any argument against the conspiracy becomes an argument for the conspiracy, as contrary evidence was planted and absent evidence was removed. But you might be able to sow a seed of reality that could rear its rational sprout years later.

Debunking isn't about being contrary (no it isn't! yes it is!); it's about exposing shams and falseness, and it can be good debate practice or just plain fun. Apart from having fun, the primary goal should be the defense of quality science because it's such an amazingly useful tool for discovery and progress.

Lastly, imagination can be inspiring, useful, and enjoyable; but when fiction is presented as fact, it is open to criticism, and your health or wealth can be in jeopardy from bunk.
