Successful change depends on how people react, not just the action itself
In 1847, Ignaz Semmelweis observed that women in a maternity ward were dying at an alarming rate. Doctors were moving from autopsies to delivering babies without washing their hands, unknowingly spreading deadly infections. When Semmelweis introduced handwashing, mortality rates dropped. But his colleagues rejected the idea, feeling blamed and attacked. And once they stopped the practice, death rates soared again. Years later, Florence Nightingale promoted handwashing during the Crimean War, framing it as a way to combat “bad air.” Unlike Semmelweis, she didn’t blame the doctors, and they accepted the change, saving lives.
This example demonstrates the first principle of lasting change: change isn’t just an action; it’s a reaction. If people feel attacked or manipulated, they’ll resist – even if the change benefits them. Semmelweis’s direct approach triggered defensiveness, while Nightingale’s framing resonated with the doctors’ beliefs, making the change easier to accept.
For change to last, it must align with someone’s values. If people sense the change serves your interests more than theirs, they’ll push back. This resistance, or “reactance,” happens when people feel forced, threatening their sense of autonomy.
To avoid this, present the change in a way that aligns with what people care about. Show them how it benefits them without attacking their beliefs. When the change feels like a natural extension of their choices, they’re more likely to embrace it, just as Nightingale’s doctors did.
