As parents, it’s essential we teach children how to think clearly and confidently. One key principle in logic that often trips people up is this: exceptions don’t disprove the general rule.
For example, the general rule “birds can fly” is true. Most birds do fly. But penguins and ostriches don’t. Does that mean the whole idea is wrong? No, obviously. These are exceptions, not evidence that the general rule itself is false.
Why this matters
We often hear people say, “That’s not true – I know someone who…” or “Well, what about this one case…?”
But relying on exceptions to argue against well-established patterns can lead to faulty thinking and poor decision-making.
On a societal level, this sort of fallacious reasoning is often used to avoid addressing serious issues, for example around race and inequality.
Take this example: someone says, “Systemic racism affects Black people’s job opportunities.” Another person replies, “That can’t be true because I know a Black man who’s a CEO.” That response points to an exception, but it doesn’t address the existence of racialised barriers that are backed-up by robust data.
Helping Children to spot this Error
We can teach our children that noticing an exception doesn’t mean throwing away the whole pattern.
Encourage them to ask:
- Does this example represent the majority or is it a rare case?
- Are we talking about an exception, or a change in the whole pattern?
- Is this being used to distract from a bigger truth?
Teaching children that exceptions don’t disprove general rules helps them stay calm and clear-headed in debates, interpret statistics better, and engage in real-world issues thoroughly.
