\par{\textbf{Biased \par\textbf{Biased  Approaches to Life Events} 6a.In reviewing descriptions of incidents, errors and case studies we commonly noted the academic discipline, profession, and background of investigators biased their choices of significant data and their ignoring data. They ignored  aspects of events obvious to us. Somewhat later we noted we were also doing the same thing. One of our tasks would be to break down observations into smaller units that could be globally described but closely observed. Another was to state our biases and in designing tools aim to push the user to observe aspects features  they quite naturally ignore.
