We agreed on a basic method for answering the question, using the tetrad of media effects
as the main tool. The tetrad is a well-tested instrument developed to show simultaneously
) ways technologies and media have impact on society. The outline of the tetrad form was recognizable soon as Lincoln's original text showed that cell phones mean the end and beginning of certain social effects. We set out to extend this analysis with further praxis, trying out some additional iterations of the "ending/beginning scenarios." So we pulled together a small team of players to build on Lincoln's initial inspiration in each of the four dimensions of the tetrad. A tetrad analysis asks four basic questions, What does the cell phone ...enhance? ...reverse? ...retrieve? ...obsolesce?
It attempts to answer this by displaying the four areas all at once, to be viewed around the central technology. Thus
We strove to transform these simple probes into acts of praxis
and "answer by showing." So each quadrant of the tetrad becomes a task
(or tasks). This tetrad is shown by the cumulative effect of these praxes and answers the question What do cell phones mean?
A way to read this proof is look at the media below with the "smaller" view setting. The grid is laid out as a tetrad. The Center point is the photo of Lincoln's iPhone (itself containing broadcast tower Sutro). The four quadrants of the tetrad radiate out from it with enhance at top left, reverse at top right, retrieve bottom left, obsolesce bottom right.
