## IQ and mental health

It’s possible that I’ve written about this before, but I’m too lazy to check. I just saw this tweet by Baal about what he calls the “Aaron Swartz syndrome” (of brilliant people lost to mental illness because they put too much pressure on themselves).

(and yay, tweets are publicly visible again)

Baal’s tweet here is about a mutual classmate who we lost over a decade ago.  And this tweet triggered off a thought that I’ve had regarding pattern recognition, and which I might have written about earlier.

Fundamentally, what makes us intelligent is our ability to see patterns. Before the advent of modern “advanced linear algebra”, the difference between giving instructions to a human and to a computer was that the latter had to be incredibly specific. The human, on the other hand, could get approximate instructions, and then quickly see patterns in what they were observing, and get the job done.

Even a lot of “advanced linear algebra” works the same way. You give it a bunch of data, and it uses some mathematical transformations to “learn patterns” about the data, and then looks for these patterns in hitherto unseen data to make predictions. So what makes “artificial intelligence” intelligent is that it can use maths to divine patterns.

I remember taking this Mensa test when in college. It was all about pattern recognition. Four images given, and you need to figure the best fifth image to complete the sequence. That sorts. And Mensa claims to be a “club for the insanely intelligent”, and they use pattern recognition as a means to identify the more intelligent humans.

I can go on but I think I’ve provided sufficient evidence arguments on how intelligence is basically about pattern recognition. The more intelligent you are the better you are at identifying patterns.

Now what does it have to do with mental health?

The answer lies in false positives.

The problem with being good at pattern recognition is that sometimes you can tend to overdo it. You start seeing patterns that don’t really exist. I must mention here that I got over my extremely long-term and fairly deep depression back in 2012 when I was asked to deliver a few lectures on logical reasoning – explaining to my lecturees that correlation does not imply causation convinced me of the same, and I started feelingbetter.

So – because you are good at pattern recognition, you end up seeing too many patterns. I remember this from business school – I saw a bunch of people eating lunch together and thought I’ll go eat with them. And then I noticed a pattern among the set of people (something silly to the effect of “they are all from Section A, and taking this marketing elective”) that didn’t apply to me. And suddenly I decided I didn’t belong there and didn’t go to sit with them.

On that day I remember this happening multiple times, and I finally ate my lunch alone. Now thinking back, this was silly of me – and I had voluntarily brought upon myself unpleasant thoughts (“I don’t belong in this group”) and loneliness.

This is just one example – such things regularly happened through the decade of the 2000s. I would see demons (patterns, basically) where none existed. I would overthink decisions like crazy. I would bring loneliness upon myself. I would make random correlations, that would only serve to depress (“oh, my lucky shirt hasn’t dried, so I won’t be able to do well in today’s exam” types).

Generalising – what you see is that the better you are at seeing patterns, the more the spurious patterns you see (in advanced linear algebra, we call this “overfitting”). And these spurious patterns end up affecting you, and clouding your judgment. And making you less capable of leading life.

I keep thinking, and saying, that my engineering class has been especially badly affected by mental illness. In the class of 30 odd, we’ve lost two people to suicide already (including the person Baal mentioned in his tweet), and know of several others who had mental illness severe enough to either drop out, or take semesters off.

And given that the class was largely made up people from the extreme right tail of the distribution in a highly competitive entrance exam, I’m coming to believe that correlation exists – all of us being superior pattern recognisers, have been prone to recognising spurious patterns, and many have fallen prey to mental illness, to different extents.

## Taking Intelligence For Granted

There was a point in time when the use of artificial intelligence or machine learning or any other kind of intelligence in a product was a source of competitive advantage and differentiation. Nowadays, however, many people have got so spoiled by the use of intelligence in many products they use that it has become more of a hygiene factor.

Take this morning’s post, for example. One way to look at it is that Spotify with its customisation algorithms and recommendations has spoiled me so much that I find Amazon’s pushing of Indian music irritating (Amazon’s approach can be called as “naive customisation”, where they push Indian music to me only because I’m based in India, and not learn further based on my preferences).

Had I not been exposed to the more intelligent customisation that Spotify offers, I might have found Amazon’s naive customisation interesting. However, Spotify’s degree of customisation has spoilt me so much that Amazon is simply inadequate.

This expectation of intelligence goes beyond product and service classes. When we get used to Spotify recommending music we like based on our preferences, we hold Netflix’s recommendation algorithm to a higher standard. We question why the Flipkart homepage is not customised to us based on our previous shopping. Or why Google Maps doesn’t learn that some of us don’t like driving through small roads when we can help it.

That customers take intelligence for granted nowadays means that businesses have to invest more in offering this intelligence. Easy-to-use data analysis and machine learning packages mean that at least some part of an industry uses intelligence in at least some form (even if they might do it badly in case they fail to throw human intelligence into the mix!).

So if you are in the business of selling to end customers, keep in mind that they are used to seeing intelligence everywhere around them, and whether they state it or not, they expect it from you.
