字幕表 動画を再生する 英語字幕をプリント Affirming a Disjunct is a logical fallacy that occurs in a situation where there are two possibilities (aka disjuncts), and the confirmation of one is incorrectly taken to deny the other. This fallacy follows the format: "A or B is true; A is true; therefore, B is not true." It's a fallacy because both A and B could be true simultaneously. Everyday example: A person said, "It's raining outside, so either I take an umbrella or I will definitely get wet; since I'm taking an umbrella, it's impossible for me to get wet." This statement implies a false dichotomy: either taking an umbrella or getting wet, suggesting these outcomes are mutually exclusive. However, this is an oversimplification. In reality, taking an umbrella doesn't inherently prevent the possibility of getting wet, as other factors like wind could still lead to one getting wet.
