In corporate and government bureaucracies, the standard method for making a presentation is to talk about a list of points organized onto slides projected up on the wall. For many years, overhead projectors lit up transparencies, and slide projectors showed high-resolution 35mm slides. Now "slideware" computer programs for presentations are nearly everywhere. Early in the 21st century, several hundred million copies of Microsoft PowerPoint were turning out trillions of slides each year.
Alas, slideware often reduces the analytical quality of presentations. In particular, the popular PowerPoint templates (ready-made designs) usually weaken verbal and spatial reasoning, and almost always corrupt statistical analysis. What is the problem with PowerPoint? And how can we improve our presentations?
Thy Godlike crime was to be kind,
To render with thy precepts less
The sum of human wretchedness,
And strengthen Man with his own mind;
But baffled as thou wert from high,
Still in thy patient energy,
In the endurance, and repulse
Of thine impenetrable Spirit,
Which Earth and Heaven could not convulse,
A mighty lesson we inherit.
Like thee, Man is in part divine,
A troubled stream from a pure source;
And Man in portions can foresee
His own funereal destiny;
His wretchedness, and his resistance,
And his sad unallied existence:
To which his Spirit may oppose
Itself—and equal to all woes,
And a firm will, and a deep sense,
Which even in torture can descry
Its own concenter'd recompense,
Triumphant where it dares defy,
And making Death a Victory.
