A Good Decision Can Still Have a Bad Outcome
We often tell ourselves: “It worked, so it was a good decision.” And when things go wrong: “I should never have made that decision.” Both conclusions can be wrong.
A decision is made with the information, circumstances and probabilities available at that moment. The outcome arrives later. Between the two sits uncertainty.
The Outcome Trap
Imagine two people investing in the same opportunity. One researches the business, understands the risks, considers alternatives and invests an amount they can afford to lose. The other invests because everyone around them is doing it. The investment falls. Both lose money. But only one made a good decision.
The outcome was identical. The decision quality wasn’t.
The Decision Quality Test
What did I know at the time? Don’t use information that became available later to judge your earlier thinking.
What alternatives did I consider? A decision becomes stronger when meaningful alternatives have been examined.
What risks did I knowingly accept? Every meaningful decision contains uncertainty. The question is whether the uncertainty was understood.
Would I make the same decision with the same information today? If yes, a bad outcome doesn’t necessarily mean you made a bad decision.
The Lesson Most People Miss
Bad outcomes teach us something. But they don’t always teach us, “Don’t make that decision again.” Sometimes they teach us that the decision was reasonable but the assumptions were wrong. Or that the process was weak. Or that a known risk was underestimated.
These are very different lessons. Confusing them can make us worse decision makers.
Don’t Confuse Luck With Judgment
A successful outcome can reinforce bad thinking. You take a reckless bet, it works, and you conclude you have good judgment. The opposite can happen too. You make a careful decision, it fails, and you lose confidence in your judgment.
Both are dangerous. Good outcomes can disguise weak judgment, while bad outcomes can unfairly punish sound judgment.
The MyMentr Decision Principle
Judge the decision with the information available before judging it with the outcome that followed.
The outcome matters. It tells us what happened. But the decision process tells us why we chose what we chose. That is where learning begins.
The real question isn’t “Did it work?” It is “Was this the best decision I could reasonably make with what I knew then?”
Good decisions improve judgment. Good outcomes merely make us feel right.
