Why people use dark patterns

Rather than deceiving users, enable
them to do what you’d like them to do.

simplicity of the target behavior, you increase Ability.”

must never be made to work.”

Clarifying techniques

Use fewer props Add only
the necessary to your UI

todoist.com

Use a memory hook Be
consistent

Visually clarify the props Make
it clear what everything does

Visually clarify the layout (That
says it all)

Make the hidden visible If
it needs to be there, put it there.

Eliminate time lags Design for
performance

Eliminate interruptions Avoid distractions from
the task at hand

Procedural directness
Design fluid procedures

Delight vs Frustration
