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.
