One of the questions we get asked a lot is “what’s the difference between psych testing and predictive analytics”. So today we’re going to unpack this a little bit and look at how the two differ, and where they are similar
Psych Testing
Psych testing has been around for decades. It’s an old-school form of predictive analytics. You look at a big group of people who are in the same role and figure out what’s common with their profiles, define a set of questions to test for the common attributes for that role and then apply that as a broad-based test for anyone who is applying for that same role.
What makes psych testing compelling?
It’s been around for a while, so people are familiar with the practice.

What makes psych tests limiting?
It’s generally expensive, cumbersome to interpret, and based on a very big assumption that if you fit the profile you will be successful in the role.
Psychological assessments have long been used to identify ‘hidden talent’ or ‘potential’ in people with limited work experience. Whilst these traditional assessments have reduced the hiring and promotional error rates, they take time to analyse, are costly, and are built off competencies inherently imbued with bias. It gives a suggestion that you are a fit, but we know that this rarely correlates to actually being successful in the role.
Psych tests are testing your ability to do a test. That’s it. Traditional psychological assessments do not link to actual performance in the role, nor do they have any self-learning functionality. There is no performance data that feeds into psychological assessments and therefore they have limited predictive power.
Predictive Analytics
In the context of Sapia, we use actual performance data to predict a candidate’s likelihood of success in the role they have applied for. The applicant completes an online questionnaire, but in-between the questions asked and the applicant’s responses is a data model. This statistical model draws on many different objective data points to predicts a candidate’s success in the role.
This also enables an efficient and immediate feedback loop about the actual performance of the hired candidate, improving the accuracy of the predictive model over time. Very quickly the predictive model that you use to select high performers becomes completely customised for your business. You build your own bespoke Intellectual Property, which becomes even more valuable with use.
Where does the prediction come from?
We all try to find patterns to help us make decisions, whether it’s ‘this restaurant looks busy so it must be good’, to ‘this person went to the same university as me, so they must know what they’re talking about’. We are often blinded by our innate cognitive biases, such as our tendency to overweight the relevance of our own experience. We end up in a tourist trap eating overcooked steak because that’s what everyone else was doing.
Our predictions are based on analysing objective data – someone’s responses to a set of questions, compared to the objective performance metrics for that same person in the role. This is a much more reliable and fairer way to make the decision. The democracy of numbers can help organisations eliminate unconscious preferences and biases, which can surface even when those responsible have the best of intentions.
Alchemy of high performers
We work closely with the recruiter or hiring manager to drill down into the qualities of a high performer, and then structure a bespoke application process to search for this. This could be a high level of empathy for customer service or the drive and resilience needed in sales.
Like all AI, our system improves with data. It learns what kind of hires drive results for your business, and then automatically begins to look for this with future applications. Ultimately, the more applicants that apply, the better it gets in identifying which people best match your requirements. And the longer you leverage our system, the more effective it gets.
Hopefully, that’s given you a good overview of where we differ, and what some of the advantages of implementing this into your recruitment process. Still, looking for more?

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.
