Frank and I have considered how to manage these issues. We have set-tled on a specifc strategy. We have determined to pursue the mini-mization of these particular classes of distortion by calling upon alarge number of people who were physically present and participatedin or observed some of the events that are herein described. A few arenames that are widely recognized in the present day feld of NLP; mostare people who are unknown and largely inactive with respect to thepatterning of the NLP of today – people who have no particular clearknown agenda. Mark carefully what they report.You will fnd in this book the voices of people who moved resolutely,wandered, and/or often stumbled (most of all the co-authors of thisbook) through these events, each of whom carried with them specifcpersonal agendas and perceptual flters which ensured that their per-ceptions and thus subsequently their reconstructed memories of theseevents would be quite distinct, especially with the passage of time (nowsome 40 years). Many of these diferences arise through the ubiqui-tous and selective perceptual fltering that necessarily results from thestrong limitations of the bandwidth of consciousness (7 + or – chunksof information).I would venture that few of the distortions that occur in such recon-structions are deliberate. Tis lack of explicit awareness of the flteringand its consequences, and the unconsciously motivated personal agen-das of the people responsible for these deviations from what actuallyhappened (now largely unknowable), makes such distortions all themore problematic, both with respect to the task of discovering whatthe distortion is/was and what it is/was a distortion of – that is, devia-tions from what actually happened.But surely one of the most obvious and powerful conclusions from thedevelopment and deployment of patterning over the last four decadesin NLP, and easily verifed in the reader’s own experience, is the aston-ishing diversity in the descriptions that emerge from any single eventwhen described from the distinct perceptual positions of the peoplewho directly participated in or witnessed the event in question.
