There are some common logical fallacies on the site I have noticed. I don't want to pick on any particular user because we allĀ mess up and use logical fallacies, it's often just easier to recognize when others use them, than when we use them ourselves. There are a few I am going to focus on now, as they have been jumping out to me lately.
False Dichotomy
This is the fallacy of saying that you must choose between only two options, without considering all of the possibilities. some examples are as follow;
1. You are either republican or Democrat
you can be a commie
2. your favorite ice-cream is either chocolate or vanilla.
maybe you hate all ice-cream equally
However sometime it can be trickier to recognize, for example;
1. If you do not go to college you will not get a good job.
There are lots of jobs that a person could enjoy where college is not a prerequisite.
2. Frank called out sick to work yesterday but he has a sunburn and posted pictures at the beach, so he is lying.
You can be too sick to focus on a repetitive task all day and still be physically capable of laying down on a blanket near water.
Since we want to show a real life example we can all look at, take a look at the following thread; https://www.debateart.com/forum/topics/11448-people-in-my-family
In that thread and please click on it, the threads author is implying that his grandmother cannot both be anti illegal immigration and care about immigrants. This is not true. Obviously a person can simultaneously care about illegal immigrants and think that illegal immigration should be stopped.
I won't go too far down the rabbit hole of why this type of logic occurs, but I think a lot of it has to do with the fact that psychologically most liberals have 2 guiding moral principles, while conservatives have 5 and so there is a genuine difficulty in understanding the balancing act taking place.
In the following thread; https://www.debateart.com/forum/topics/9501-were-not-coming-for-your-guns-they-said
It is heavily implied that you can either be for restrictions on gun ownership that go beyond the status quo or be pro 2nd amendment. This is a clear false dichotomy, as you can be both things at one time.
Most of the time in the real world and especially on DART, this is how you will see the logical fallacy present. You won't see it directly stated, but with assumed premises and with implied premises. If you see a false dichotomy, in a debate, in the forums, or in real life than point it out. Even if you agree with the conclusion of whoever made the logical fallacy, just point out the flaw in the logic so you can help them make a better case for your position.
