The ability to accurately observe, assess, and interpret others’ strengths, weaknesses, motivations, and potential. Practical interpersonal acumen requires curiosity, emotional intelligence, critical observation, and a willingness to revise early impressions.
“Knowing others is intelligence; knowing yourself is true wisdom. Mastering others is strength; mastering yourself is true power.” Lao Tzu
Barriers to sizing people up
Bias towards equality: Leaders may resist recognising individual differences, driven by anti-elitist beliefs or an over-reliance on the moral argument that “everyone is the same.”
Impatience: Leaders who rush interactions or judgments may miss nuances that reveal people’s true qualities and capabilities.
Inexperience: A lack of tenure or exposure to diverse teams or situations can leave leaders unskilled in identifying strengths, weaknesses, and potential.
Superficial observations: Poor listening and limited observation can prevent a leader from truly understanding individuals’ behaviours, motivations and capabilities.
Cognitive biases and stereotyping: Preconceived notions can skew perceptions and lead to unfair or incomplete evaluations of individuals.
Instant judgements: Snap decisions based on limited data can solidify into fixed views, ignoring evolving or deeper insights about a person.
Failure to adapt assessments: Leaders who do not revisit or revise their initial appraisals may misjudge how people will perform in new circumstances.
Time constraints: A lack of prioritisation for studying team members can result in shallow appraisals and missed opportunities to leverage individual strengths effectively.
Over-simplistic models: Leaders may rely on narrow or outdated frameworks for understanding human behaviour, leading to inaccurate assessments.
Reluctance to make tough decisions: Avoiding difficult decisions about individuals’ roles or capabilities can result in a lack of critical appraisal.

Enablers of sizing people up
Challenge your biases: Examine your assumptions and where they come from. Read about personality theories or human diversity to broaden your understanding and become more open to leveraging individual strengths.
Start with self-awareness: Understanding others begins with understanding yourself. Engage in 360° feedback to uncover your own tendencies and use this as a benchmark to understand others.
Study the people around you: Observe colleagues closely to identify their preferences. Predict how individuals will act in certain situations and measure your accuracy over time to refine your understanding.
Identify what truly matters: Identify the key skills and competencies that differentiate exceptional performance for specific tasks rather than focusing on broad characteristics.
Stay open longer: Avoid locking in judgments too quickly. People are complex and evolving; stay flexible and willing to revise your opinions as new information becomes available.
Seek feedback: Discuss your evaluations with trusted colleagues to uncover blind spots. Understanding where your assessments differ from theirs can reveal patterns in your perceptions.
Calibrate your assessments: Participate in group assessment activities to compare your observations with others and align your perceptions with broader perspectives.
Hone your skills: Use tools like effective interviewing techniques to become a more attentive listener and detecting strengths and motivations with greater precision.
Embrace the tough conversations: Provide constructive feedback and address negative behaviours. View this responsibility as a necessary aspect of leadership that fosters growth and accountability.
Align People to the right roles: Recognise that equality doesn’t mean sameness. People thrive when tasks match their strengths. Provide everyone the best opportunity to be even better.
“If one does not understand a person, one tends to regard him as a fool” C.G. Jung

When was the last time you avoided a difficult conversation about performance—what held you back?
How often do you test the accuracy of your evaluations with trusted colleagues?
