The converse fallacy of accident is the reverse. [definitional]
The converse fallacy of accident is the reverse of dicto simpliciter. It occurs when we move carelessly or too quickly to a generalization. It occurs when we construct a general rule from an inadequate number of incidents. … The fallacy appears when one or two decisions are used to make a quantum leap to a conclusion that these decisions form a rule with general application.
