There is a need to know how some conclusion was arrived at. What was the thinking involved? There is a need to know reasons and background. 1/5 your decision to pull out of the consortium. 1/5 the delay in settling this invoice. 1/5 the choice of Sardinia for a holiday. 1/5 the choice of law as a career. 1/5 the remark you made about my being stingy. 1/5 the investment in China. 1/5 the need to use the de Bono code. Code 1/5 might occasionally be used after code 1/4 if it seems that he reaction needs explaining. It is also possible to use both together as: 1/4, 1/5. This would indicate:" Give me your reaction but also explain the reasons behind this reaction". The elaboration and explanation does not simply have to be a logical support for a position. It is more a matter of establishing the context in which the position has emerged. "I do not trust him." "We have had bad experiences in China." "Consumer products are not our business." These are not fully logical reasons but they do explain why a position has been taken. It is much more a matter of "explaining" a position rather than "justifying" the position. Adequate detail is specifically requested.
