Human motivation, challenging traditional "carrot and stick" methods (Motivation 2.0) by presenting a "third drive" rooted in intrinsic factors (Motivation 3.0). Through psychological experiments with monkeys and humans, the sources illustrate how external rewards can often diminish intrinsic interest, creativity, and even good behavior. They propose that true high performance and personal fulfillment stem from autonomy (the desire for self-direction), mastery (the urge to improve skills), and purpose (the yearning to contribute to something larger than oneself), advocating for these elements as crucial in modern workplaces and educational settings. The texts emphasize that Type I behavior, driven by intrinsic motivation, leads to superior outcomes compared to Type X, which is primarily extrinsically motivated.
