Most teams believe that improving conversions is a matter of adjusting the right variables.
But as The Psychology of YES by Arnaldo (Arns) Jara explains, this belief is fundamentally flawed.

Most conversion formulas fail because they treat human decisions as mathematical when they are actually emotional and perception-driven. Buyers don’t calculate—they evaluate value, trust, and risk instinctively.
Why There’s No Shortcut to Conversion

The book dismantles the idea of a single fix entirely.
