Errors in reasoning that invalidate an argument.
LOGICAL
FALLACIES
errors of logic: the conclusion doesn’t really “follow from” (is not supported by) the premises. Either the premises are untrue, or the argument is invalid.
FORMAL FALLACIES
Take many forms and are widespread
in everyday discourse. Very often they
involve bringing irrelevant information
into an argument or they are based on
assumptions that, when examined,
prove to be incorrect.
INFORMAL FALLACIES
7 COMMON LOGICAL FALLACIES:
SLIPPERY SLOPE
APPEAL TO FORCE
APPEAL TO PITY
BANDWAGON
PERSONAL ATTACK
HASTY GENERALIZATION
POST HOC
It is an argument that suggests taking a minor action will lead to major and sometimes ludicrous consequences .
SLIPPERYSLOPE
When force, coercion, or even a threat of force is used in place of a reason in an attempt to justify a conclusion.
APPEAL TO FORCE
Happens when you manipulate someone’s feelings of pity or guilt in order to get them to support a point of view.
APPEAL TO PITY
Argues that one must accept or reject an argument because of everyone else who accepts it or rejects it - like peer pressure
BANDWAGON
Occurs when someone tries to refute an argument by attacking the character of a person instead of attacking the ideas of the argument.
PERSONAL ATTACK
Occurs when someone makes a conclusion or generalization based on a small sample size or pas experiences with no sufficient evidences.
HASTY GENERALIZATION
A fallacy where one reasons that since an event occurred before another, then the first event caused the other.
POST HOC
A fallacy where one reasons that since an event occurred before another, then the first event caused the other.
