How far is 5 from 4? Does art take you from 4 to 5? Does MAGIC happen between 4 and 5?

I was intrigued, not long ago, to see a tweet by Dr. Prabhakar Raghavan that went “Berkeley Study: Half-Star Change In Yelp Rating Can Make Or Break A Restaurant  nonlinear outcomes from linear(?) inputs“.

Anderson and Magruder at Berkeley observed Yelp ratings and tried to see if they impacted the likelihood of a restaurant being fully booked at peak dinner time (between the hours of 6 and 8 pm).

What they found was that:

An extra half-star rating causes restaurants to sell out 19 percentage points (49%) more frequently, with larger impacts when alternate information is more scarce

Moving from 3 to 3.5 stars reduces the likelihood of availability from about 90% to 70%. A fourth star reduces the likelihood of  availability further to 45%, and that possibility drops to 20% at 4.5 stars

So, the answer to the first question seems to be “A lot farther than you’d think” or “About as far as 4 is from 1” !

Now I am going to show you something else that is equally amazing!

The above economics result is very similar to what is being talked about in this XKCD cartoon on online star ratings!

Take a close look at the cartoon and you will see that the cartoonist is saying much the same thing as the economics researchers.

How did the artist hit it right on the head?

Just how did he do it?  (maybe the cartoonist read the research paper – the guy’s a scientist so it could have happened).

But could it just be that good artists are also incredibly perceptive and intelligent people?

Does art take you from 4 to 5?

I don’t have the answer to that, but I am going to point you to an intriguing paragraph in the book “Transforming Education through the Arts”.

“We found that compared with typical scientists, Nobel laureates are at least 2 times more likely to be photographers; 4 times more likely to be musicians; 17 times more likely to be artists; 15 times more likely to be craftsmen; 25 times more likely to be writers of non-professional writing, such as poetry or fiction; and 22 times more likely to be performers, such as actors, dancers or magicians.”

(From Page 7 of “Transforming Education through the Arts” in the article “The social and educational costs of neglecting the arts”, citing as the source: “Root-Bernstein and Root-Bernstein 2010: 4”).

So, maybe the answer to the second question is ‘maybe‘.

I say ‘maybe’ because there is another explanation.

In software, we have a saying that goes:

80 percent of the features take 20 percent of the time.  The last 20% of the features take 80% of the time.

However, this 80/20 rule seems to apply to many things in life.

You can be a better singer than 80% of the world quite easily.  It might even be possible to become a better singer than 97% of the world with a bit more work.  But it takes infinitely more effort to get from 97% to 99%.  To reach those levels of perfection takes enormous dedication and persistence.

This is the case in every art, and in every craft, and in every area of science, and in every area of technology.

Products become magical when you put in that enormous effort that takes it from 97% to 99% of perfection.

Dancers become magical when they go from 97% to 99%.

We all heard the story of Steve Jobs obsessing over the details of the iPhone even during sessions of chemotherapy.

Cartoonists become magical when …

You get the idea.

So maybe it’s not about art …

Or about science …

Or about technology …

Maybe it’s about having the strength, resilience and stamina to get you to the very top of the mountain and the obsession to keep going …

Maybe that’s what makes all the difference in any area of human endeavour – the intense effort and drive that only very obsessed people are capable of putting in is the magic (or madness) that takes something from 4 to 5.

Maybe that’s why 5 is so far from 4.
