Eat Meat... Or Don't.

Roughly 95% of Americans don’t appear to have an ethical problem with animals being killed for food, yet all of us would have a serious problem with humans being killed for food. What does an animal lack that a human has that justifies killing the animal for food but not the human?

As you start to list properties that the animal lacks to justify eating them, you begin to realize that some humans also lack those properties, yet we don’t eat those humans. Is this logical proof that killing and eating animals for food is immoral? Don’t put away your steak knife just yet.

In Eat Meat… Or Don’t, we examine the moral arguments for and against eating meat with both philosophical and scientific rigor. This book is not about pushing some ideological agenda; it’s ultimately a book about critical thinking.

A logical fallacy is an error in reasoning, such as a failure to evaluate evidence correctly.

A cognitive bias is a psychological state in which someone tends to believe things that are not well supported, or tends to overestimate one's own side while underestimating the other side.

A person with a cognitive bias might be more likely to commit a fallacy.

A logical fallacy is a mistake in an argument that renders the conclusion unwarranted from the given premises. It is an erroneous line of reasoning that makes the conclusion not follow from the premises because it is not supported by them.
A cognitive bias is a built-in inclination towards certain ideas, beliefs, and conclusions that are not logical but are the product of innate predispositions and heuristics.
In other words, a logical fallacy is the mistake in reasoning, while a cognitive bias is the inclination to do this mistake.
Example: say person A sees somebody from country X assaulting a person, and they conclude that all people from country X are aggressive, mean people who assault others and that citizens of country X have a trend and societal problem of physical attack. person A here committed the logical fallacy of overextended outrage<>, which is the statistical error in reasoning of taking statistically rare incidents done by an individual of a group and erroneously concluding that such incidents are a trend and commonplace among people from that group. This logical fallacy is the result of the cognitive bias called the group attribution error<>, which is the tendency to generalize properties of an individual in a group and mistake them as representative of the entire group.

A logical fallacy identifies some specific failure(s) in the logical structure of someone’s argument(s). Cognitive bias is a failure in someone’s rational capacity to weigh and assess evidence or the merit of specific propositions, causing them to accept particular premisses for their argument(s) that almost everyone else views as obviously mistaken or even downright absurd.

A "logical fallacy" is a fault of an argument that can be assessed objectively as such.
"Cognitive bias" is often a subjective opinion about someone's state of mind, usually applied to an opponent (and not his/her argument) and near to a fallacy of ad hominem , if asserted as part of one's argument.
