Research Team Finds a Link Between Extroverts and Positive Language

A brand new research by psychologists from Nanyang Technological University, Singapore (NTU Singapore) reveals a correlation between extroverts and their phrase selections. The discovering means that on-line character prediction instruments want higher linguistic indicators to enhance digital advertising methods. Marketing corporations have already begun engaged on these instruments.

In our fashionable world, these corporations make the most of predictive algorithms to forecast what prospects need in line with on-line behaviors. Digital advertising corporations additionally benefit from on-line knowledge and machine studying to higher perceive the psychology behind shoppers’ selections. Of course, this analysis can present perception into methods to enhance focused promoting.

For occasion, extroverts might reply higher to advertising, which corresponds with their character. Retailers may then enchantment to those shoppers with extra extroverted, inventive language. However, on-line character prediction instruments utilized by advertising companies right this moment want some enchancment. They lack accuracy as a result of they solely apply in sure conditions and functions.

Lead investigator of the research, Associate Professor Lin Qiu from the Psychology program on the NTU School of Social Sciences, stated,

“Current machine learning algorithms for personality prediction can seem like a black box — there are many linguistic indicators that can be included in their design, but many of them are dependent on the type of computer application used. This may lead to biases and overfitting, an error affecting the performance of the machine learning algorithms. This begs the question — how should we create robust and accurate personality predictions?”

The analysis found a hyperlink between extroverts and their tendency to decide on particular sorts of phrases. The research revealed that extroverts tended to make use of extra optimistic language and “social process words.”

How psychologists found the correlation between extroverts and phrase alternative

Using textual content evaluation instruments, psychologists outline optimistic emotion phrases as these portraying an pleasant emotional state. Words that describe positivity embody ‘love,’ ‘happy,’ ‘blessed,’ ‘beautiful’ or ‘nice.’ Social course of phrases describe these which include personal pronouns apart from ‘I.’ These phrases additionally present social intentions or targets, similar to ‘meet,’ ‘share,’ and ‘talk.’

“This is the first time a relationship has been established between extroverts and their tendency to use the two categories of words. As it is a small correlation, we believe that stronger linguistic indicators are needed to improve machine learning approaches, amid rising interest in such tools in consumer marketing,” Assoc Prof Qiu stated.

The analysis was printed within the Journal of Research in Personality in December 2020. The NTU team said that these findings could help marketers develop better linguistic predictors for machine learning algorithms. This will, in turn, enhance software tools for personality prediction.

How the team carried out the study

Prior studies reviewed by the NTU psychologists have found a link between extroversion and specific word choices. Extroverts tend to have more positive emotions and enjoy socializing more than introverts. The team positively associated this personality trait with increased usage of “positive emotion” and “social process” words. However, the strength of this correlation varies across the studies exploring extroversion and language.

To prove the strength of these linguistic predictors, the team reviewed 37 studies on the topic. They categorized extroversion using internationally recognized personality type questionnaires. In the future, the NTU team wants to study the relationship between extroverts and other word choices.

Currently, machine learning and predictive tools can help companies and marketers in business endeavors. However, the NTU psychologists say that the design of these models could use improvement. They hope their research will help marketers better understand how certain words can appeal to different personality types. Furthermore, they expect the study will bring about improvements in machine learning tools used for personalty prediction.

These same tools can likely help predict words that introverts use as well. Of course, most people fall somewhere on the spectrum between introverts and extroverts. Personality can change depending on many factors, and therefore, can’t be reduced to just word choices. However, there are certain traits that introverts and extroverts exhibit, which give their underlying personality away.

Final ideas: a crew of psychologist finds a hyperlink between extroversion and optimistic language

This doesn’t imply introverts are inherently dangerous; the truth is, way more analysis is required on this subject. However, a meta-analysis by the NTU crew discovered that, usually, extroverts have a tendency to make use of extra optimistic language. Their optimism and love of exterior stimulation might clarify their tendency to decide on particular phrases.

In conclusion, researchers discovered that they used extra “positive emotion words” and “social process words.”

These phrases describe a nice emotional state or present social intentions. Of course, research on introverted language also needs to be performed to have a foundation for comparability. However, it’s fascinating to see how phrase alternative can correlate with character traits. The crew hopes that their analysis will assist enhance machine studying instruments sooner or later.
