Bullshit Detector

A hypothetical, mental device that represents a person's ability to detect deception, dishonesty, corruption, fraud, insincerity, hypocrisy and falsity in others. A person with a "built-in bullshit detector" usually knows when someone else is lying, or putting on a false front for appearances. These people are not easily conned, coerced, lied to, tricked or manipulated because their "bullshit detector" allows them to avoid falling prey to such things. These people are also often slightly cynical, extremely perceptive, intuitive, shrewd and just generally highly intelligent. Disagreeing with someone or something doesn't mean you have a "bullshit detector". A lot of people think they possess a "bullshit detector", because they dislike or complain about a lot of things, or enjoy sharing their, often unpopular, opinions (in all caps) online. In reality, these people just have opinions, they are not actually good at detecting deception. In fact, they are probably more likely to be victims of the very same bullshit that someone who actually has a bullshit detector, is trying to make them aware of, but due to their reactionary natures, obtuseness, and lack of bullshit-detecting capabilities, they are either unwilling or incapable of accepting that they've been bullshitted on.
