HomeĀ /Ā EssaysĀ / Who Feels More Alone?
Imagine you live in a world with only two types of people. Introverts (iās)Ā and extroverts (eās).
In this world introverts are happy to be alone so they want to meet a friend only once every 14 days.
Extroverts on the other hand love to be around people, they want to hang out with a friend once every 2 days.
Letās take a closer look at our protagonists:
Introvert | ||||||
Wants to meet a friend once every | 14 | days | ||||
Probability he wants to meet a friend today | 7.14% |
Extrovert | ||||||
Wants to meet a friend once every | 2 | days | ||||
Probability he wants to meet a friend today | 50.00% |
IĀ“s and eĀ“sĀ also have something in common. They have short term memory loss. Everyday at midnight their brain does a full reset. So they never remember what happened yesterday.
Now take a guess: Which personality type feels more alone? Introverts or extroverts?
What does this question even mean? Let's say you're an introvert. You wakeĀ up one morning and wantĀ to meet a friend. But when you call your friends, they donāt want to hang out with you. That day you will go to bed feeling alone.
Did you take a guess? Maybe you picked extroverts, because they need more human interaction in general. Or you picked introverts, because they shoot themselves in the foot by being such loners?
To answer this question I calculated the probability of meeting a friend today for each friend group mix.
What is a āfriend group mixā?
Each table cell is calculated like this: probability_self * sum_probability_friends.
x-axis = number of extroverted friends, y-axis = number of introverted friends
x-axis = number of extroverted friends, y-axis = number of introverted friends
We can see that for extroverts the probability of meeting a friend today rises much faster than for introverts. Extroverts need less friends to have a high probability of meeting a friend today. But, if you are like me, your brain doesn't know how to work with percentages. So let's turn these % into days.
Now I calculated how many days iāsĀ and eās have to wait until they meet a friend.

Think about how many introverted and extroverted friends you have. Then check the charts above: How many days do you (theoretically) have to wait until you meet a friend?
Did you also get 1095 days š ? But hold on! Where do the 1095 days for 0 friends come from?
I chose to limit the number of waiting days to a maximum of three years. Otherwise the 0/0 cell would show the number infinity for iĀ“s and eĀ“s. This would have messed up the charts and following calculations.
Why did I choose three years (or 1095 days)? I guess in three years everybody should be able to make and meet at least one friend.
If you haven't met a friend in three years, let's hang out quickly so my charts are correct š.
Unfortunately the previous calculations still don't tell us who feels more alone. For that we need the relative difference between what a person wants and what a person receives.
An analogy:
Who do you think is pissed off more? Ben šØĀ or Lisa š©? I think it's Ben. Because even though, just like Lisa, he earns 50ā¬ less than what he wants. His relative difference (50%) is much higher than Lisas relative difference (5%).
Back to our own problem: Below you can see the same ārelative difference calculationā for iās and eās and all friend group mixes.

x-axis = number of extroverted friends, y-axis = number of introverted friends
Wow, both tables are exactly* the same. This means that introverts and extroverts are both feeling alone theĀ same.
*The only difference is the first cell. Why is that? Earlier in the essay I told you I set a maximum waiting time of 1095 days if somebody has no friends at all š .
Now because this āzero friends limitā is exactly the same for iĀ“s and eĀ“s the relative difference for extroverts is much higher.
This means if you lock an extrovert in a single prison cell for 1095 days he will feel much more alone than an introvert. That's a no brainer. You probably already knew that.
I know I`m not. And since IĀ“m the mayor ofĀ thisĀ āthought experiment worldā, I'm making up one more rule: Extroverts have more friends than introverts. Which might also be true in real life?
To simplify this last chapter I calculated how alone iās and eās feel depending on the number of friends they have. Hereās this calculation for all possible friend group mixes:

x-axis = introvert or extrovert, y-axis = number of friends, colored cells = āfeeling alone factorā
Now the numbers look different from what we saw before. Why is that? If an introvert has 1 friend, this one friend can either be an introvert or an extrovert. So the average āfeeling alone factorā for one friend is: (1300% + 100%) / 2 = 700%
As you can see, the feeling alone factor for an introvert with 1 friend is higher than for an extrovert with 2 friends. We made progress. Introverts feel more alone than extroverts š„². Ā
But to be honest this feels too much like cheating. So I kept thinking: Isn't there something I might have forgotten? Yes, there is: We become friends with people who are like us. Which means extroverts have more extroverted friends & introverts have more introverted friends.
If iās and eās only have friends of the same kind, the new table looks like this:
Only friends of same kind | ||
Friends | š“āā ļø Introvert | š¦ Extrovert |
1 | 1300.00% | 100.00% |
2 | 625.93% | 33.34% |
3 | 401.65% | 14.29% |
4 | 289.81% | 6.67% |
5 | 222.96% | 3.22% |
6 | 178.59% | 1.58% |
7 | 147.07% | 0.78% |
8 | 123.58% | 0.39% |
9 | 105.45% | 0.19% |
10 | 91.06% | 0.10% |
x-axis = introvert or extrovert, y-axis = number of friends, colored cells = āfeeling alone factorā
As you can see, introverts feel shockingly more alone š±. If both, iās and eās have only one friend, introverts feel 12 times more alone. If they both have 10 friends, introverts feel over 900 times more alone.
Now there's only one question left to ask: Are you an extrovert and want to hang out in 14 days?
