The real reason why new pop music is so incredibly bad

You have probably heard that Pink Floyd recently published their new album Endless River. Will this bring back the wonderful world of good music after the endless awfulness of the popular music scene in the last 20 years or so? Is good music, as we know it from the 60s and 70s, back for good? The reasons behind the alleged endless awfulness of pop music these days suggest otherwise. We shouldn’t be throwing stones at new music but instead at our inability to like it.

Pink Floyd 1973

When we were young we learned to appreciate Pink Floyd.

Daniel Levitin was asked at a recent music psychology conference in Toronto why old music is amazing and new music is awful. He believed that modern record companies are there to make money. In the olden days, on the other hand, they were there to make music and ready to hold on to musicians which needed time to become successful. More interestingly, he reminded the public that many modern kidz would totally disagree with the implication that modern music is awful. How can it be that new music is liked by young people if so much of it is often regarded as quite bad?

Everything changes for the better after a few repetitions

The answer to the mystery has nothing to do with flaws in modern music but instead with our brain. When adults hear new music they often hate it at first. After repeated listening they tend to find it more and more beautiful. For example, Marcia Johnson and colleagues (1985) played Korean melodies to American participants and found that hearing a new melody led to low liking ratings, a melody heard once before to higher ratings and even more exposure to higher than higher ratings. Even Korsakoff patients – who could hardly remember having heard individual melodies before – showed this effect, i.e. without them realising it they probably never forget melodies.

This so-called mere exposure effect is all that matters to me: a robust, medium-strong, generally applicable, evolutionarily plausible effect (Bornstein, 1989). You can do what you like, it applies to all sorts of stimuli. However, there is one interesting exception here. Young people do not show the mere exposure effect, no relationship between ‘repeat the stimulus’ and ‘give good feeling’ (Bornstein, 1989). As a result, adults need a lot more patience before they like a new song as much as young people do. No wonder adults are only satisfied with the songs they already know from their youth in the 60s and 70s. Probably, when looking at the music scene in 2050 the current generation will equally hate it and wish the Spice Girls back (notice the gradual rise of 90’s parties already).

I listened to it –> I like it

So, when it comes to an allegedly awful present and great past, ask yourself: how deep is your love for the old music itself rather than its repeated listening? Listen repeatedly to any of a million love songs and you will end up appreciating it. Personally, I give new music a chance and sometimes it manages to relight my fire. Concerning Endless River, if it’s not love at first sight, do not worry. The new Pink Floyd album sure is good (depending on how many times you listen to it).

PS: Yes, I did hide 29 Take That song titles in this blog post. Be careful, you might like 90’s pop music a little bit more due to this exposure.

Memory training boosts IQ

Is the IQ set in stone once we hit adulthood? ‘Yes it is’ used to be the received wisdom. A new meta-analysis challenges this view and gives hope to all of us who feel that mother nature should have endowed us with more IQ points. But is the training worth it?

Intelligence increases in adults

I have previously blogged about intelligence training with music (here). Music lessons increase your intelligence by round about 3 IQ points. But this has only been shown to work in children. A new paper shows that adults can also improve their IQ. Jacky Au and colleagues make this point based on one big analysis incorporating 20 publications with over 1000 participans. People did a working memory exercice, i.e. they trained the bit of their mind that holds information online. How? They did the so-called n-back task over and over and over again. Rather than explain the n-back task here, I just invite you to watch the video.

Increasing memory, increasing intelligence

Of course you cannot change your intelligence if you only do the task once. However, once you do this task several times a week over several weeks, your performance should increase, which shows that you trained your working memory. However, you will also improve on seemingly unrelated IQ tests. The meta-analysis takes this as a sign that actual intelligence increases result from n-back training. Working memory training goes beyond improvements on working memory tests alone.

The catch

So, the training is effective. It increases your intelligence by three to four IQ points. But is it efficient? You have to train for around half an hour daily, over a month. Such a training regime will have a considerable impact on your life. Are three to four IQ points enough to compensate for that?
