What are the Big Five?
The Big Five is the scientific foundation of how Retorio understands behavior. Personality is usually defined by the set of behaviors, feelings, and thoughts that arise from a person’s biological and environmental state. While there’s no set definition behind the word “personality”, researchers over the past decades have made a respectable effort to optimize the assessment of an individual’s real character traits by different methods.
Within this process, five dimensions seem to have emerged along which a person can be characterized: the so-called Big Five of Personality (McCrae and John, 1992). Of course, as is common in scientific research, no model stands without critique. However, the Big Five have been widely reproduced across various (cultural) contexts, gender, age and ethical groups and showed to be equally independent of the language of assessment. The model captures the following traits:
- Openness
- Conscientiousness
- Extraversion-Introversion
- Agreeableness
- Neuroticism (emotional stability)
It has to be stressed, that these five categories of personality show a range within each. For example, no one is 100% introverted or 100% extroverted. Individuals tend to sit somewhere in the middle. Retorio builds on this science through its Warmth and Competence framework, reading observable behavioral cues to coach reps, agents, and managers on how they come across in real conversations.
Openness to experience
Reps who score high on this trait tend to be intellectually curious, willing to try new approaches, and more creative. Those who score lower prefer proven methods and can find rapid change harder to adapt to.
How it shows up in customer conversations
High-openness reps experiment with new discovery questions and fresh framing. Lower-openness reps lean on structured, repeatable talk tracks.
Coaching focus
Retorio coaches high-openness reps with stretch scenarios and room to improvise, and supports lower-openness reps with clear frameworks and step-by-step practice.
Conscientiousness
This reflects how well a person aligns with responsibility, organization, and goal-setting. It includes self-control and how deliberately someone makes choices. Lower scorers tend to be more spontaneous and flexible.
How it shows up in customer conversations
Highly conscientious reps prepare thoroughly, follow up reliably, and keep their commitments to customers. Lower scorers move fast but can miss follow-through.
Coaching focus
Retorio reinforces disciplined preparation and follow-up, and helps lower-scoring reps with short-term goals and clear next steps that build momentum.
Extraversion-Introversion
This spectrum describes how people gain energy. More introverted reps draw energy from reflection and ideas. More extroverted reps gain it from interaction and variety. No one is purely one or the other.
How it shows up in customer conversations
Extroverted reps open easily and build rapport quickly. Introverted reps often listen more closely and ask sharper, more considered questions.
Coaching focus
Retorio coaches extroverted reps to slow down and listen, and helps introverted reps project confidence and drive the conversation when it counts.
Agreeableness
A person high on this trait shows more prosocial behavior such as cooperation, friendliness, and politeness, with strong empathy. Lower scorers tend to be more direct and competitive.
How it shows up in customer conversations
Highly agreeable reps build trust and warmth easily but can struggle to hold price or push back. Lower scorers negotiate firmly but can come across as cold.
Coaching focus
Retorio helps highly agreeable reps stay assertive under pressure, and coaches lower scorers to lead with warmth alongside competence.
Neuroticism
People who score high tend to experience more negative or anxious states, while those who score low stay calmer under pressure. It is a long-term emotional tendency that can make demanding situations feel more challenging.
How it shows up in customer conversations
Reps with higher emotional stability stay composed during objections and difficult calls. Higher scorers can feel more pressure in high-stakes moments.
Coaching focus
Retorio builds confidence through repeated, safe practice on tough scenarios, so reps stay composed when the real conversation gets hard.
Why personality science matters for coaching
One of the strengths of this model is that it reliably predicts outcomes in social and professional settings such as career motivation, job satisfaction, and job performance.
Just as in the theory of evolution there is no simply good or bad trait, only traits well or poorly adapted to a given environment, the same is true at work. A rep who is direct and competitive brings different strengths to a negotiation than one who leads with empathy. Neither is better in the abstract. What matters is how each person behaves in the moments that drive revenue, retention, and customer experience.
This is why Retorio coaches behavior rather than sorting people. The Big Five gives a scientific map of how someone tends to act. Retorio uses the Warmth and Competence framework, built on this science, to show reps, agents, and managers how they come across in real conversations and where small behavioral shifts improve results. The coaching is grounded in observable behavior, not labels.
How Retorio reads behavior objectively
Human judgment of another person's behavior is inconsistent. Research shows that people diverge strongly when they rate someone's character, and first impressions often miss the traits that matter most for performance, such as conscientiousness and emotional stability. Snap judgments are also shaped by bias and by how much attention a person can pay while holding a conversation.
Retorio removes that inconsistency. Instead of relying on one manager's subjective read, Retorio analyzes observable behavioral cues from a rep's own practice conversations and gives the same objective, structured feedback every time. That consistency is what makes coaching fair, repeatable, and scalable across a whole team.

Does observable behavior predict performance?
Two ways to read personality
There are essentially two ways to assess personality: ask people to describe themselves, or observe how they actually behave.
Self-assessment asks people to rate statements about themselves, for example:
- I have no problem starting conversations
- I pay attention to detail
- I stay calm under pressure
Observation instead reads a person's visible behavior: how they open a conversation, handle an objection, or respond under pressure.
These differ by definition. Self-assessment reflects internal, less observable motives and intentions and can be skewed by how we would like to see ourselves. Observation reflects public, visible behavior. Both have limits, but for coaching, behavior is what counts.
Why observable behavior wins for coaching
Observer ratings of personality provide substantial additional validity over self-reports in predicting job performance, improving prediction on average by 13% across traits. Across all Big Five traits, observed behavior accounts for more variance in job performance than self-reports do. The effect is strongest for conscientiousness, where observation explains 6.7% more, and agreeableness, where it explains 5.8% more.
Some behavior is read almost instantly. Extraversion, for example, is accurately perceived after only a 50ms exposure to a person's face, because we evolved to read others' expressions to anticipate their behavior.
This is the scientific basis for how Retorio coaches. Because observable behavior predicts performance better than self-report, Retorio reads the behavioral cues that signal warmth and competence in real conversations, then coaches reps, agents, and managers on the specific shifts that improve conversion, ramp time, retention, and customer experience.
