The Genetic Fallacy
If I am made up of DNA, am I a double helix?
If one thing comes from another, do they have to share traits? This might seem like a convenient bias to have. However, do redwood trees seem to have much in common with their seeds? The genetic fallacy is the assumption that anything with an origin in one thing is highly likely to share traits.
What should I do?
This one is easy to do by accident, but also simple to overcome with a little extra thinking. Remember that things need not have the same traits as their origin. Think of the Volkswagen company; it was founded by the Nazi labor front. Does that make it a Nazi company now? Of course not, we would have to examine its present merits by themselves to determine that. The best thing to do for this fallacy is to try to examine why a thing has the traits it has without using its origin as an end-all answer.
