What we miss when we focus on the average | Am I Normal? with Mona Chalabi

Transcriber:

When we think about data, we usually think about averages.

Average height, average salary,

average number of hours spent on video calls.

It’s tempting to focus on these neat little summaries of our world.

But the world is a lot messier than these averages can make it out to be.

So instead, I look for the outliers.

They can offer a better reflection of this chaos we call life.

And they can offer a different perspective

on the things that we think we understand.

[Am I Normal? with Mona Chalabi]

Take, for instance, the stats around teens and cigarettes.

According to the CDC, between 1997 and 2019,

the percentage of American high school students who smoked plummeted

from 36 to just six percent.

That seems like a pretty big win,

but when you break apart the data and look at the outliers,

it is a totally different picture.

Among American Indian and native Alaskan students,

cigarette usage is much higher than that six percent average.

It comes in at a sizable 21 percent.

All other racial and ethnic groups were in the single digits.

So what first seemed like this great success story

is actually an indicator of how much work we need to do

to reach some of the most marginalized communities.

In general, when we present data as a scatterplot,

the average would usually look like this.

And where there are outliers,

the typical approach is to undervalue them,

to see them as a deviation from the average

or from what society thinks is normal.

But I like to call these outliers “lost birds.”

It's a nickname I use for something or someone who has gone astray.

If you look hard enough,

you'll find that these lost birds pop up everywhere.

Like my mom, for example.

She doesn't like being on camera, so this puppet will have to do.

She's a soft spoken, hijabi woman who isn't much bigger than this puppet.

Because of that, it's easy for some people to underestimate her.

But don't let those first impressions fool you.

“In my generation,

we used to listen and accept what they tell us.

'Do what you're told.'

But when I got older,

I just changed and I started to argue my point and get what I want."

My mom's a retired doctor, an avid ugly-dress maker,

a mother of two and a grandmother of none.

Though she spends a fair amount of time trying to speak that into existence,

"I think for every mother, for her daughter, she wants a grandchild."

(Laughter)

"Sorry, Mona."

Moving on.

My mom is also a lost bird.

"Me?"

She has, statistically speaking, gone astray.

"Yeah, but it was a good deviation."

Back in the late '70s,

my mom left Iraq and moved to the UK

to further her medical training and practice.

She's among the four percent of people born in Iraq who now live abroad.

By the early 2000s,

just three percent of UK doctors with her experience

were non-white and practicing in her speciality.

My mom is a lost bird because she is an outlier.

She's one of the rare few to leave her home country

and even rarer still among her medical peers.

We all think that the people that we love are special,

and there is some truth to that.

But it’s worth considering the ways that we are all lost birds.

Because when we focus on the average and we ignore the outliers,

we lose all of the richness and insights that those stories provide.

But when we dig into the deviations, we get to see the bigger picture.

One from a bird's-eye view.
