In addition to the above you will need to keep your overall -material as brief as possible. When you become overly long- or poorly organized you will loose their attention. The objective means of verification include, but are not limited to, measurement. This may seem like a trivial example since everyone -recognizes today that it is incorrect. Examples include hoaxes like the Piltdown man as well -as current debates on the existence of 'cold fusion'.
Facts are often fuzzy.
This means that we only use enough- detail to resolve the decisions that we need to make. We may compare this to the accuracy used to measure the -speed of runners in Olympic events. This fuzziness may seem like splitting hairs until we begin- to examine situations that we encounter on a day to day basis. We- again probably would respond yes. Clearly, resolving the level of detail and fuzziness of- facts can become a full time job.
