How do polls guess what millions of people think?

The Soup Spoon Test
How do polls guess what millions of people think?
Imagine trying to guess what flavor of ice cream every single person in your entire country likes best. ~~You can't ask

Imagine trying to guess what flavor of ice cream every single person in your entire country likes best. You can't ask everyone — there are millions of people! That would take forever, and by the time you finished, half of them would have changed their minds. So how do polls figure out what huge groups think by asking just a tiny slice?

Here's the trick: if you do it right, a small group can speak for a big group. It's like tasting soup — you don't slurp the whole pot to know if it needs salt. One spoonful tells you everything, as long as you stirred the pot first. Polls work the same way. They ask maybe a thousand people to represent millions.
