As part of my work, I often have to put together PowerPoint presentations. One rule for effective slides is to show some data…for instance, a graph…and then make three points or conclusion.
Not two points.
Not four points.
Definitely not ten points.
But three. It’s like a golden number.
And it is effective.
However, three is not perfect for every situation. Yes, it may be ideal for executives in business, but it would be ridiculous in life to force every presentation of information into three bullet items.
