I will spend next couple of months attempting to implement what I’m learning. There is such a lot though, I think I might have to do their course.

'A good behavioral science basis and countless practical examples. Recommended!'

'BAM! Online Influence by Bas Wouters and Joris Groen falls on the doormat. A pound of inspiration about behavioral psychology and online success. With a recommendation from Robert Cialdini, wow... But rightly so, it turns out. Because this is persuasion psychology at its best: scientifically based, clearly explained and (very) practically applied. BJ Fogg's model gives you a clear framework, and with the authors' checklists at hand, it's actually idiot-proof. So I have the confidence that I can do something with it too! Also not unimportant: finally another weighty management book with humor! In short: read, laugh and apply. Rightfully No. 1 at Managementboek.nl.'

Russian translation published by Byblos:

Тут вы, возможно, запротестуете: погодите-ка, но если люди уже хотят что-то сделать, к чему их убеж- дать? Но именно здесь и кроется проблема. Тот факт, что мы чего-то хотим, не означает, что мы автоматически это сделаем.

Дизайнеры (проектировщики) поведения в своей рабо-те следуют двум важным психологическим истинам:

• Мы нечасто что-то делаем, если нас к этому не побуждают.
• Если что-то становится слишком трудным, мы быстро отступаем.

Вы можете это признать для себя. Или, возможно, предпочтете этого не делать… Как бы то ни было, назван- ными качествами – пассивностью и отсутствием упор- ства – гордиться трудно.
