Think about the last time someone explained why something works the way it does — a rule at school, a historical event, why a relationship ended. That first explanation felt pretty solid, right? Maybe you never questioned it again. That’s not a coincidence.
When we hear an explanation first, it becomes our reference point. Every other explanation gets measured against it, often without us realizing. The first one feels like the baseline, the ‘normal’ one. Later explanations feel like they have to prove themselves.
Here’s where it gets interesting. Research published through PubMed Central found that younger people tend to assume there’s one correct explanation for things — and that learning is just a process of adding more true facts to that original explanation. It’s only later that most people start to realize that two equally smart, equally qualified experts can look at the same evidence and reach completely different conclusions. That shift doesn’t even happen all at once, and it tends to show up in some areas of life before others — for example, people often become more open to competing viewpoints in matters of taste or opinion before they apply that same openness to more fact-based topics.
So what does this mean for you? It means the person who explains something to you first has real power — whether they earned it or not. A parent, a teacher, a YouTube channel, a friend’s older sibling. Whoever gets to you first shapes how you judge everything that comes after.
That’s not always bad. First explanations are often good ones. But sometimes they’re incomplete. Sometimes they’re flat-out wrong. And because of the way our brains work, a wrong first explanation can make a correct one feel suspicious.
The fix isn’t complicated, but it takes a little practice. When you hear an explanation — especially about something that matters — ask yourself: is this the first time I’m hearing this? If yes, hold it loosely. Don’t treat it like the final word. Look for other takes. See if the explanation still holds up when you hear it from a different angle or from someone with a different perspective. If it does, great. If it falls apart, you just saved yourself from carrying around a wrong idea for years.
Being the kind of person who can say ‘I thought I understood this, but let me actually check’ — that’s not weakness. That’s how you actually get things right.
