Which type of logical fallacy is indicated when a speaker implies that future success is guaranteed based on past performance alone?

The type of logical fallacy indicated when a speaker suggests that future success is guaranteed solely based on past performance is known as "Post Hoc." This fallacy arises from the assumption that because one event follows another, the first event must be the cause of the second. In this context, the speaker believes that because past achievements have occurred, they will continue to happen in the future without considering other influencing factors or the possibility of change.

This reasoning neglects the complexity of circumstances that can affect outcomes over time and overlooks the impact of variables that may differ from the past. It essentially implies that a causal relationship exists where none may be valid, making it a flawed argument in the logic of predictions or projections.
