Welcome back to Truth, Lies & Work, the award-winning workplace podcast where behavioural science meets organisational culture. In the corporate world, we are obsessed with personality. We use DISC, Myers-Briggs, and Enneagrams to "colour-code" our colleagues and predict who will be a great leader. But what if we’ve been looking at the wrong data? In this episode, we sit down with Juliette Alban-Metcalfe, a Chartered Occupational Psychologist and CEO of Real World Group. Juliette is at the forefront of leadership research, building on the groundbreaking work of her mother, Professor Beverly Alimo-Metcalfe. Juliette argues that personality only explains a tiny fraction of leadership success. Instead, the real "magic sauce" is behaviour—the specific, observable actions that leaders take to engage their teams and foster success. In this episode, we discuss: Personality vs. Behaviour: Why what you do matters infinitely more than who you are according to your personality test results. The "Accidental Manager" Trap: Why founders and technical experts often struggle to transition into leadership and how 360-degree feedback can bridge the gap. Predictive Validity: The science behind why leadership behaviours can predict up to 60% of a team's motivation and fulfilment. Psychological Safety: How to use assessments to build trust and development rather than fear and judgement. Actionable Advice for Leaders: Two simple things every leader can do today to immediately improve team engagement. If you’ve ever felt like you’re "not a natural leader" or if you're an HR professional frustrated with the lack of ROI from personality workshops, this episode is a masterclass in the science of what actually works. 🔗 Connect with Juliette – LinkedIn: Juliette Alban-Metcalfe – Website: Real World Group 📬 Connect with Al & Leanne – LinkedIn: Truth, Lies & Work – Al Elliott: LinkedIn – Leanne Elliott: LinkedIn – Email: [email protected] – Book a call: https://savvycal.com/meetleanne/chat 🧠 Mental Health Support UK & ROI — Samaritans: Call 116 123 or visit https://www.samaritans.org UK — Mind: Call 0300 123 3393 or visit https://www.mind.org.uk US — Suicide & Crisis Lifeline: Call or text 988 or visit https://988lifeline.org Australia — Lifeline: Call 13 11 14 or visit https://www.lifeline.org.au Global Helplines — https://findahelpline.com Truth, Lies & Work is part of the HubSpot Podcast Network, the audio destination for business professionals.
