The principle. When uncertain, humans copy what similar others did. The closer the "similar," the stronger the pull.
Why logo walls underperform. A wall of 50 logos says "lots of people use us." But the prospect can't tell which one is like them. Specificity beats volume.
The 1-1-1 story format. One peer + one number + one outcome.
