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 comments sections about pseudoscience, grand conspiracies, quackery, or the supernatural? If yes to any of the above, then you have come to the right place. Welcome! If you are new to skepticism (not to be confused with cynicism), I recommend that you start with Tools for assessing claims, Cognitive Biases and Traps, and Logical Fallacies.
Debunking can be an easy sport yet 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 Why People Don't Realize They're Incompetent for an explanation). And in the case of grand conspiracy believers, any argument against the conspiracy becomes an argument for the conspiracy, as contrary evidence was planted and absent evidence was removed. Sneaky! 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 and intuition can be inspiring, useful, and enjoyable; but imagining doesn't make it so, and intuition is but a fallible prediction; and when fiction is presented as fact, it is open to criticism, and your health, wealth, or peace of mind can be in jeopardy from bunk.
