The domains covered in the idea space included foregrounding of information to increase awareness, visual and audio notification, providing haptic feedback (accentuating real-world effects), reputation systems (publicizing driver reputation / behavior), offering trade-offs (gas consumption, speeding tickets), rewards and incentives (insurance incentives for monitoring), and playing on emotions.
Assuming that this sort of feedback wouldn't do much to discourage a phisher from sending an attack (it would be difficult to convince them to attach electrodes to their fingers for instance), perhaps it could be used to alert the recipient of the potential dangers of "clicking on the URL"?
As the idea of simple visual indicators to show the risk level of emails has been done, perhaps:
- mouse vibration alerts recipient of risk (maybe for really obvious phsishes the mouse just refuses to work and sits their shaking crazily?)
- paying users to NOT click on URLs in suspicious emails.
- dynamic graphic showing their bank account balance dropping
- publicly listing those who do fall prey
