Not many studies have been conducted to quantify the relationship that may exist between personality and musical preferences. In fact, un recent meta-analysis seemed to question whether the relationship was very strong.
However, through the use of more modern techniques and a broader understanding of musical taste, it is suggested in a recent study published in Social Psychological and Personality Science that musical preferences may reflect Big Five personality traits.
The Big Five
Previous studies on music and personality have limitations in not being able to fully measure listening habits, because they are based on self-reported preferences and small samples.
However, in the present study, several Spotify users were asked to participate by showing their listening habits over three months, including information about the genres and moods of the music they listened to.
To get a more complete picture, some questions were asked to build a more nuanced understanding: Do you discover new music or listen to old favorites? Are your tastes diverse? Do you have regular listening habits?
Along with these measures, study participants were asked to complete the Inventory of the Big Five, a 44-item questionnaire that measures the five personality traits:
- Openness to experience (inventive/curious vs. consistent/cautious)
- Awareness (efficient/organized vs. extravagant/careless)
- Extraversion (sociable/energetic vs. solitary/reserved)
- Kindness (friendly/compassionate vs. challenging/uncaring)
- Neuroticism (susceptible/nervous vs. resistant/confident)
To understand how these personality scores relate to music preferences, a machine learning model was trained to predict someone's personality using only their preferences and demographic information.
Those who rated themselves as more 'open to new experiences' tended to listen to more classical, Afropop or 'sentimental' music (e.g. 'Freddie Freeloader' by Miles Davis, 'April Come She Will' by Simon & Garfunkel). Listening to bluesy or 'melancholic' music (e.g. 'Take Care' by drake, 'Karma Police' by Radiohead) has an inverse relationship with self-assessment of 'emotional stability', while people who listen to Death Metal or 'aggressive' music (e.g. 'Boss' by Lil Pump, 'Last Resort' Papa Roach) tend to have fewer 'pleasant' self-evaluations, while people who listen to Jazz or Country have more.
People whose results identified them as extroverted tended to listen to others' playlists more, which could indicate greater trust in musical suggestions from their social networks. Self-rated introverts, on the other hand, tended to dig deeper into an artist's catalog, listening to more tracks from each artist they discovered.

Discovered in the debris of the hydrogen bomb.
Officially known as Brookesia nana, either B. lullaby for short, the new species It is so small that it is believed to survive on a diet of mites and springtails, an order of hexapod arthropods close to insects.
About the size of a sunflower seed, the newly described creature from Madagascar may already be critically endangered. Finding such a small reptile also raises interesting questions about the lower limits of vertebrate body size.
Brookesia nana
Like other chameleons, This small reptile has a tongue that it can project to catch its prey.. It hunts during the day on the jungle floor and retreats to the safety of the blades of grass at night.
So far, scientists have observed only two individuals: a male and a female, each of which was captured in 2012, on an expedition to a group of mountains known as the Sorata massif.
The researchers suspect that this nanochameleon could receive the title of the smallest reptile in the world. The fact that only two individuals were found makes it difficult to generalize about the findings. Other chameleons of this species may be larger or smaller, just as humans may be of different heights.
Its closest competitor is a creature called Brookesia micron, a species of tiny chameleon that made its debut in 2012, photographed on the head of a matchstick.

Most accidents are caused by human error, simply because our brain cannot process as many inputs nor maintain attention for as long. Thus, autonomous vehicles will eventually make our roads safer.
However, people trust human drivers more than autonomous vehicles, reveals a new study published in the magazine Risk Analysis. This bias is called blame attribution asymmetry.
Risk analysis
Semi-autonomous vehicles (semi-AVs), which allow humans to supervise driving and take control of the vehicle, are already on the road. However, when there is an accident, we are inclined to think that the fault the machine or the vehicle manufacturer had it before the human driver.
Researchers led by Peng Liu, associate professor at the School of Management and Economics at Tianjin University, conducted experiments to measure participants' responses to hypothetical semi-AV shocks. When a crash was caused by a vehicle's automated system, participants assigned more blame and responsibility to the automation and its manufacturer and indicated that the victim should be compensated more, compared to a crash caused by a human driver.
They also judged that the crash caused by automation was more severe and less acceptable than one caused by a human, regardless of the severity of the crash.
Liu and his colleagues call this bias against automated systems blame attribution asymmetry. It indicates the tendency of people to overreact to shocks caused by automation, possibly due to the higher negative affect, or feelings and emotions, evoked by these shocks. Negative emotions such as anger can amplify attributions of legal responsibility and blame.
To change people's negative attitudes about semi-AVs, Liu maintains that "public communication campaigns are very necessary to transparently communicate accurate information, dispel public misconceptions, and provide opportunities to experience semi-AVs." .
