Evaluating arguments


Arguments can be evaluated by following four steps:


  1. Begin by deconstructing the argument so that you can identify its premises, the assumptions that underpin in, and its conclusions. 
  2. Establish whether the argument is deductive or inductive
  3. Determine whether the argument is logically valid. Does the conclusion follow from the premises? Is there any missing information or hidden premises that would be required to make the conclusion valid? 
  4. If you feel that the conclusions are valid, check that the premises are true


Evaluating arguments can be difficult at first. For an example of evaluation in action, watch this video which evaluates a common argument connected to climate change produced by staff at the University of Queensland (and if you're interested you can read their full paper examining this issue).
