Document Summary

Common mistakes in argument reconstruction (1) improper wording: jim studies regularly. Since most people who study hard will do well in school, it"s likely that jim will do well. (this is an inductive argument bc it"s likely he will do well) There is a difference between studying regularly and studying hard. Common mistakes in argument reconstruction (2) missing premises. If you leave out one or more premises you misrepresent the argument which affects your evaluation of it: try your best to include all the premises explicitly given by the author. Where possible, reword the explicit premises so that they conform to one of our standard patterns: always include parenthetical justifications for conclusions and double check them to see if they actually make sense. Common mistakes in argument reconstruction (3) unnecessary premises: don"t include non-argumentative material like descriptive writing in the standard form argument.
