The science of how radio stations introduce new songs

As the major contributor of content on radio is music, the station ought to be playing hit numbers so that listeners keep tuned in. But how can radio stations afford to play only hit songs, if they are more costly? And what about the promotions of new songs? How do new songs get played on radio stations? And how do they become a hit? That got us digging. Here’s what we found.

There’s a company named Polyphonic HMI – a bunch of artificial intelligence experts and statisticians based in Spain – who has created a program called Hit Song Science. Don’t kill us for this. Hit Song Science analyses mathematical characteristics of a tune by comparing the tempo, pitch, melody, chord progression, and other factors against thousands of hit songs stored in Polyphonic HMI’s database. They predicted the success Norah Jones’s Come Away with me that won 8 Grammys, Santana’s Why don’t you and I that reached number three on Billboard charts. (We don’t know what song they predicted incorrectly.)

The program also predicted the success of a song called Hey ya by hip-hop group OutKast in 2003. When industry folks heard Hey ya, they liked it and thought it would become a huge hit. But when the data came in about listeners across radio stations, a huge number of listeners tuned out within the first thirty seconds itself. What went wrong?

One of the pioneers in studying why and how songs become sticky, Rich Meyers, says, “Sometimes radio stations do research by calling up listeners and playing a snippet of a song, and listeners will say, I’ve heard that a million times and I’m totally tired of it. But when it comes on radio, your sub-conscious says I know this song, I can sing along. Your brain secretly wants that song, because it’s so familiar to everything else you’ve already heard and liked.”

Areas of our brain that process music – auditory cortex, thalamus and superior parietal cortex – are designed to seek out patterns and look for familiarity. Music after all is complicated with numerous tones, pitches, overlapping melodies, etc. Our brains crave familiarity in music, because familiarity is how we manage to hear without becoming distracted by all the sound. That’s why songs that sound ‘familiar’ – even if we’ve never heard them before – get sticky.

The problem wasn’t that Hey ya was bad. The problem was that it wasn’t familiar. So radio stations used the trick of sandwiching Hey ya between familiar hit songs to mitigate risk. If stations don’t take risks with new songs people will stop listening. On the other hand, listeners want songs they already like. So by sandwiching them between already hit songs, stations make new songs familiar as fast as possible. Jiten, partner at Boing recording studio, says, “radio stations mitigate risk by playing new songs that are well promoted on audio-visual media like the TV as well.” Makes sense.

Does it really take 21 days to form habits?

Does it really take 21 days to form a habit?

In the preface to his 1960 book ‘Psycho-cybernetics’, Dr Maxwell Maltz, a plastic surgeon turned psychologist wrote:

‘It usually requires a minimum of about 21 days to effect any perceptible change in a mental image. Following plastic surgery it takes about 21 days for the average patient to get used to his new face. When an arm or leg is amputated the “phantom limb” persists for about 21 days. People must live in a new house for about three weeks before it begins to “seem like home”. These, and many other commonly observed phenomena tend to show that it requires a minimum of about 21 days for an old mental image to dissolve and a new one to jell.’

Self-help authors of 21 days to this, that and everything, may have reasoned that, if self-image takes 21 days to change, and self-image changes lead to changes in habits, then habit formation must take 21 days. Although ‘21 days’ may perhaps apply to adjustment to plastic surgery, it is unfounded as a basis for habit formation. Here’s the proof:

In an 84-day study by researchers at University College London, 96 participants were asked to choose an every day behavior that they wanted to turn into a habit. They all chose something they didn’t already do that could be repeated every day like eating a piece of fruit (behavior) with lunch (cue) or doing 50 sit-ups (behavior) after morning coffee (cue).

So how long did it take to form a habit? On average it took 66 days until a habit was formed. And contrary to what’s commonly believed, missing a day or two didn’t much affect habit formation.

But here is the relevant part. There was considerable variation in how long habits took to form depending on what people tried to do. People who resolved to drink a glass of water after breakfast were up to maximum automaticity after about 20 days, while those trying to eat a piece of fruit after lunch took at least twice as long to turn it into a habit. The exercise habit proves trickiest with 50 sit-ups after morning coffee, still not a habit after 84 days.

Interestingly, there were quite large differences between individuals in how quickly automaticity reached its peak, although everyone repeated their chosen behavior daily: for one person it took just 18 days, and another did not get there in the 84 days, but was forecast to do so after as long as 254 days!

So it’s unwise to attempt to assign a number to habit formation. The duration is likely to differ depending on who you are and what you are trying to do. As long as you continue doing your new healthy behavior consistently in a given situation, a habit will form. But you will probably have to persevere beyond January 21st if you are attempting a New Year’s resolution.

Numbers don’t move us, emotions do

Numbers don't move us

Millions of Indians don’t have access to clean water, sanitation, electricity, education, healthcare, banking. The list can go on. The ones with access to all of it, including myself, are aware of the fact that millions go without it everyday. Yet it hardly moves us to do anything about it.

That’s the problem with statistics. It just doesn’t activate our emotions. Paul Slovic, a psychologist at the University of Oregon, has exposed this blind spot in our sympathetic brain. He asked people how much they were willing to donate to various charitable causes. Slovic found that when people were shown a picture of Rokia, a starving Malawian child, with emaciated body and haunting brown eyes, they donated generously to the Save the Children. However, when other people were provided with a list of statistics about starvation throughout Africa – more than 3 million children in Malawi are malnourished, more than 11 million people in Ethiopia need immediate food assistance, and so forth – the donation was 50% lower. At first glance it makes no sense right. When people are informed about the real scope of the problem, they should give more money, not less.

But what happens is that the depressing numbers leave us cold. Our minds can’t comprehend suffering on such a massive scale. That’s why we are riveted when a kid falls in a bore well but turn a blind eye to millions who die every year due to lack of clean drinking water. As Mother Teresa put it, “If I look at the mass, I will never act. If I look at the one, I will.”

Small ideas make a big difference

Small ideas make a big difference

There are lots of small everyday things that could benefit from being designed better. Things we take for granted in everyday life. But when designed well, things just work, leading to enhanced experience, satisfied customers, appropriate actionability, increased sales, etc. This post is about few of such small everyday ideas.

Like handles on doors. If there is a handle on the door, the tendency is to pull it. But almost all doors have a handle on the side it says push, too. If the door needs to be pushed, why have a handle? Simply keep it flat and we’ll push it.

When composing emails, wish there was a reminder to attach our files, when words like ‘attached’ or ‘attachment’ were found in the composed email.

‘No Parking on Odd dates 1 3 5’ and ‘No Parking on Even dates 2 4 6’ tend to be so cumbersome. We need to first think about what date it is today, then figure that its ‘No Parking’ on that side, which means we can park on the opposite side. Instead what if we had ‘Parking on Odd dates only’ and ‘Parking on Even dates only’.

Because there are two traffic signals in view at all times, one after the zebra crossing and one much ahead on the other side of the junction, we Indians always push ahead wanting to be first (in whichever race that is) therefore not stopping at the zebra crossing and not allowing pedestrians to cross. So to get cars to stop at the zebra crossing, only one traffic signal needs to be there, placed just before the stripes begin.

Instead of having to choose from financial retirement plans with complicated numbers, what if we could choose, by looking at pictures of different homes (1, 2, 3, 4 BHK) that could be bought with different levels of retirement income.

I often get asked about what mega-pixel camera on the phone is good. Fact is that we don’t understand what mega-pixels mean. What will be useful to us is the information of what mega-pixel matched what size of print. But we know this one won’t happen, else phone and camera manufacturers won’t be able to convince us to mindlessly upgrade.

Remember using the plastic card key in your hotel room to start and switch off the power. Wouldn’t it be convenient to have one in our home, so that we could start/switch off the power with one stroke and do away with the nagging feeling of not having turned off the geyser or gas or some other appliance after leaving home?

The tendency is to think of these design ideas as small (insignificant) ideas, but they are the ones that make for the most awesome product, service experiences and of course get us to behave.

Talk on Investor behaviour (Franklin Templeton)

Talk on Investor behaviour for Franklin Templeton

We spoke on Investor Behaviour at Franklin Templeton’s Independent Financial Advisor convention in Bali on 12th December.

Our presentation was about investor’s biases, heuristics and rules of thumbs. We also conducted a live auction that brought alive our irrational behaviour amongst the audience who participated in it.

The rest again is confidential material. But we will be posting many articles on behaviour – consumer, employee, shopper, investor, public that we promise.

Have an awesome year.

First ever TEDx – Q&A for VJTI

First ever TEDx talk Q&A for VJTI

We were invited for the first ever TEDx – Q&A session for VJTI engineering students and makers, on 17th September 2014 at the VJTI campus (VJTI is one of the premier engineering institutes of India having received funding from The World Bank). A big thanks to TEDxGateway’s campus connect initiative. What an awesome time we had answering questions from curious minds at VJTI about Bleep, its future, human behaviour, behaviour change, Behavioural Design and the role of technology in Behavioural Design.

Students of VJTI were shown our TEDxGateway talk on Bleep and Behavioural Design immediately followed by a Q&A session that seemed like it would have lasted hours because the questions just wouldn’t stop from the enthusiastic crowd. But of course we had to have a maximum time limit of an hour. Here are highlights of the Q&A session.

Questions naturally began about Bleep and its future. We explained to students that Bleep being a product that solved a social issue and not an individual problem, is the responsibility of the Government of India. Which is why we aren’t selling Bleep to individual customers who we believe will hardly form any numbers. Plus Bleep won’t help car manufacturers sell more cars so they won’t install it voluntarily either. After some question and answers most seemed to accept our answer but some still seemed optimistic that Bleep could be sold to individuals. May be it was their optimism bias. May be one day we’ll be proved wrong.

Students asked whether Bleep could prove to be distracting and cause accidents in emergencies. We informed them that we had tested Bleep for over 3800 km and no accidents had occurred. We also told them that according to Jeff Muttart’s study (a traffic-accident reconstructionist) in emergencies people don’t use the horn and therefore Bleep will not go off and distract them further. Jeff Muttart has pored over hundreds of surveillance videos of real-life car crashes and near-crashes. His study shows that emergency horn use is not associated with decreased accident involvement. He found that drivers never steered and honked at the same time, and usually they didn’t honk at all. About half of emergency honks were meant to chastise and came only after the danger was over. The other half were just preludes to a crash. “It really didn’t serve any purpose at all. It was just, Hey, by the way, I’m going to hit you.”

(Muttart, J., “Factors that Influence Drivers’ Response Choice Decisions in Video Recorded Crashes,” SAE Technical Paper 2005-01-0426, 2005, doi:10.4271/2005-01-0426)

Someone asked “But what will happen to people’s honking behaviour once Bleep is removed from the car?” We told them that we haven’t done the post study, but we jokingly said, “First let Bleep come into our cars. Then we’ll see what happens if its not there anymore.”

The most interesting part of the session was the discussion about Behavioural Design and behaviour change. We sensed that the students found it to be a new, unique and intriguing concept. We spoke about irrational behaviour, difference in attitudes and behaviour, why we cannot solely rely on will power for behaviour change, why most educational campaigns don’t work, how we create false memories, why we use Behavioural Design and not work towards increasing people’s self-awareness and how collaboration between engineers and designers can design new products that facilitate behaviour change.

One of the curious students having read about People Power (click on the link to read about it) before attending the session, asked us to speak about the experiment. So we obliged and told them about how human behaviour is contagious. Like right there in the auditorium once the first student raised his hand to ask a question, seeing him one by one the others followed. Soon we were asked if we had solutions for littering, spitting, eve teasing, not talking on the mobile while driving and so on. May be one day we may.

Meanwhile we told them that we had a solution for another behaviour change. We spontaneously made an offer to VJTI students and makers that we’d be happy to hire a person who could help us create a product on a project that could potentially change an aspect of our behaviour. If you are an electronic engineer, maker and are interested to change human behaviour, email us with your work at anand@brief-case.co
