Brief writers who find a credible source stating a conclusion they like may be inclined to quote a statement even if it isn't backed by a rationale. Kenneth F. Oettle, a partner at Sills Cummis Epstein & Gross and co-chair of the firm's writing and mentor programs, says if you are tempted to do this, think twice. Try instead to deduce the rationale that the source did not supply.
