Language has long been seen as a source of truth for personality – it defines who we are.
It should not be surprising then that language is also the basis of most traditional forms of personality testing.
This lexical hypothesis is a thesis, current primarily in early personality psychology. Subsequently subsumed by many later efforts in that subfield. Despite some variation in its definition and application, the hypothesis is generally defined by two postulates.
- The first states that those personality characteristics that are important to a group of people will eventually become a part of that group’s language.
- Second follows, stating that more important personality characteristics are more likely to be encoded into language as a single word.
Lexical hypothesis is a major foundation of the Big Five personality traits. The HEXACO model of personality structure and the 16PF Questionnaire and has been used to study the structure of personality traits in a number of cultural and linguistic settings.
Noam Chomsky summed up the power of language nicely:
“Language is a mirror of mind in a deep and significant sense. It is a product of human intelligence … By studying the properties of natural languages, their structure, organization, and use, we may hope to learn something about human nature; something significant …”
Language is the basis of conversational Ai and it’s very different (and way smarter) than a simple chatbot.
Where chatbots can be programmed to provide answers to basic questions real-time, so that your people don’t need to do that, these answers are canned answers to basic questions delivered through text. They lack the smarts to truly discover what your text responses say about you. The engagement between the chatbot and the individual is purely transactional.
Conversational AI is more about a relationship built through understanding, using natural language to make human-to-machine conversations more like human-to-human ones. It offers a more sophisticated and more personalized solution to engage candidates through multiple forms of communication. Ultimately, this kind of artificial intelligence gets smarter through use and connects people in a more meaningful way.
Put simple, Conversational Ai is intelligent and hyper-personalised Ai, and in the case of ‘Sapia labs’, its is underpinned by provable and explainable science. We have already published our peer-reviewed scientific research which underpins our personality science.
We published our second piece of research to explain how our Conversational Ai can predict someone’s likelihood to stay in a role.
The scientific paper may not make it to your reading table, although you can download it here (“Predicting job-hopping likelihood using answers to open-ended interview questions” ) but the business implications cannot be ignored.
According to one report, voluntary turnover is estimated to cost U.S. companies more than $600 billion a year. This is due to one in four employees projected to quit and to take a different job. If your turnover is even a few basis points above your industry average, then leveraging conversational Ai will save your business costs.
Our research used the free-text responses from 45,899 candidates who had used Sapia’s conversational Ai. Candidates had originally been asked five to seven open-ended questions on past experience and situations. They also responded to self-rating questions based on the job-hopping motive scale, a validated set of rating questions to measure one’s job-hopping motive. The self-rating questions were based on the job-hopping motive scale, a validated set of rating questions to measure one’s job-hopping motive.
We found a statistically significant positive correlation between text based answers and self-rated job-hopping motive scale measure. The language inferred job-hopping likelihood score had correlations with other attributes such as the personality trait “openness to experience”.
This is the power of true predictive Ai.
Ai, that is the bridge between HR and the business. It is this kind of quantifiable business ROI that distinguishes traditional testing with Ai models.

The AGC Debate: Are AI-Written Interview Answers a Red Flag or Smart Strategy?
Every day, we read stories of increased fake or AI-assisted applications. Tools like LazyApply are just one of many flooding the market, driving up applicant volumes to never-before-seen levels.
As an overwhelmed hiring function, how do you find the needle in the haystack without using an army of recruiters to filter through the maze?
At Sapia.ai, we help global enterprises do just that. Many of the world’s most trusted brands, such as Qantas Group, have relied on our hiring platform as a co-pilot for better hiring since 2020.
Our Chat Interview has given millions of candidates a voice they wouldn’t have had – enabling them to share in their own words why they’re the best fit for the role. To find the people who belong with their brands, our customers must trust that their candidates represent themselves. Thus, they want to trust that our AI is analysing real human answers—not answers from a machine.
The Rise of GPT
When ChatGPT went viral in November 2022, we immediately adopted a defensive strategy. We had long been flagging plagiarised candidate responses, but then, we needed to act fast to flag responses using artificially generated content (‘AGC’).
Many companies were in the same position, but Sapia.ai was the only company with a large proprietary data set of interview answers that pre-dated GPT and similar tools: 2.5 billion words written by real humans.
That data enabled us to build a world-first:- an LLM-based AGC detector for text-based interviews, recently upgraded to v2.0 with 99% accuracy and a false positive rate of 1%. An NLP classification model built on Sapia.ai proprietary data that operates across all Sapia.ai chat interviews.
Full Transparency with Candidates
Because we value candidate trust as much as customer trust, we wanted to be transparent with candidates about our ability to detect artificially generated content (AGC). As an LLM, we could identify AGC in real time and warn candidates that we had detected it.
This has had a powerful impact on candidate behaviour. Since our AGC detector went live, we have seen that the real-time flagging acts as a real-time disincentive to use tools like ChatGPT to generate interview responses.
The detector generates a warning if 3 or more answers are flagged as having artificially generated content. The Sapia.ai Chat Interview uses 5 open-ended interview questions for volume hiring roles, such as retail, contact centre, and customer service, and 6 questions for professional roles, such as engineers, data scientists, graduates, etc.
Let’s Take a Closer Look at the Data…
We see that using our AGC detector LLM to communicate live with candidates in the interview flow when artificial content has been detected has a positive effect on deterring candidates from using AI tools to generate their answers.
The rate of AGC use declines from 1 question flagged to 5 questions – raising the flag on one question is generally enough to deter candidates from trying again.
The graph below shows the number of candidates, from a total of almost 2.7m, that used artificially generated content in their answers.
Differences in AGC Usage Rate by Groups
We see no meaningful differences in candidate behaviour based on the job they are applying for or based on geography.
However, we have found differences by gender and ethnicity – for example, men use artificially generated content more than women. The graph below shows the overall completion ratios by gender – for all interviews on the left and for interviews where the number of questions with AGC detected is 5 or more on the right.
Perception of Artificially Generated Content by Hirers.
We’re curious to understand how hirers perceive the use of these tools to assist candidates in a written interview. The creation of the detector was based on the majority of Sapia.ai customers wanting transparency & explainability around the use of these tools by candidates, often because they want to ensure that candidates are using their own words to complete their interviews and they want to avoid wasting time progressing candidates who are not as capable as their chat interview suggests.
However, some of our customers feel that it’s a positive reflection of the candidate, showing that they are using the tools available to them to put their best foot forward.
It’s a mix of perspectives.
Our detector labels it as the use of artificially generated content. It’s up to our customers how they use that information in their decision-making processes.
This concept of having a human in the loop is one of the key dimensions of ethical AI, and we ensure that it is used in every AI-related hiring product we build.
