Evidence and argument
Judging support.
What kind of support
Data, expert testimony, anecdote, analogy or appeal to principle. Each has different weight, and a text usually mixes them without labelling which is which.
- An anecdote illustrates and does not demonstrate.
- An analogy is only as strong as the similarity it relies on.
Checking the fit
Ask whether the evidence actually supports the specific claim made. Support for a weaker claim is often presented as support for a stronger one.
