00:00

Are you eating a credit card’s worth of plastic every week?

00:02

Uhh…Probably not.

00:04

But if you saw headlines like this, you might worry that you are.

00:07

These days, trying to piece together what to believe can feel impossible.

00:12

But we can still find reliable, trustworthy answers

00:15

as long as we know how to look for them.

00:18

Hi, I’m Hank Green, and welcome to Crash Course Scientific Thinking.

00:21

[THEME MUSIC]

00:26

You probably already know that you shouldn’t

00:28

believe everything you read, watch, or hear.

00:30

On an internet where everyone is competing both for attention

00:33

and to control narratives,

00:35

it’s no surprise that there are plenty of distortions,

00:38

exaggerations, baseless claims, propaganda, and whatever this is.

00:42

But it’s also home to lots of good scientific information too!

00:46

So when it comes to something as important as science,

00:49

how do we figure out what’s reliable?

00:52

Well, it helps to understand how a science story like this

00:55

becomes news in the first place.

00:58

See, that CNN article isn’t the whole story.

01:00

It’s just the part we see, as consumers of science news.

01:04

*chomp*

01:06

That science news tastes bad!

01:08

Think of it like the tip of the iceberg:

01:10

there’s a lot more going on below the surface.

01:12

CNN got the details from this report by the WWF.

01:15

No, not the wrestling group from the 90s,

01:17

the World Wide Fund for Nature.

01:19

And they got it from a study they commissioned from researchers

01:22

at Australia’s University of Newcastle.

01:25

Which reported a range of possible amounts of plastic that people might consume in a week –

01:30

from a high of 5 grams, all the way down to 0.1 grams.

01:34

But the WWF only reported the high end of the range,

01:38

saying “An average person could be

01:40

ingesting approximately 5 grams of plastic per week.”

01:43

About the size of a credit card.

01:44

And that technically could be true.

01:47

It could be that much.

01:48

There's a lot of things that could be true.

01:50

It's like when the insurance company says,

01:52

“I could save you up to 15 percent or more on your car insurance.”
