The Culture of Yes: When Agreement Is the Most Dangerous Word in Business

When Agreement Masks Dissent: How hierarchy and face-saving lead leaders to mistake politeness for commitment, and how to let people challenge decisions without challenging authority.

In many workplaces, the easiest person to manage can be the hardest person to hear. Adeline Tiah argues that when hierarchy, respect, and face-saving dominate a workplace, a leader can mistake politeness for alignment and agreement for commitment. A team that says “yes” in the room may still be questioning the decision outside it -and by then, the risks have already moved downstream.

Drawing on nearly three decades of corporate leadership across technology, banking, and fintech, as well as her work coaching leaders across Asia, Adeline explores how leaders can create cultures where people can challenge decisions without challenging authority. Her forthcoming book examines why psychological safety works differently in Asian corporate environments and what leaders can do to make honesty safer without sacrificing respect. Listeners will learn how to spot false agreement, invite productive dissent, and turn disagreement into a competitive advantage.

Adeline Tiah is a Singapore-based leadership and team coach, known for helping senior leaders understand how to lead through transformation, disruption, and AI-driven change without losing trust, performance, or engagement. Her work sits at the intersection of leadership, psychological safety, team performance, and change management, with a clear point of view: business as usual is no longer enough, but speed and performance cannot come at the expense of trust.

Drawing on 25+ years of leadership experience across the telco and banking industries, including senior roles at HSBC, UOB, Standard Chartered, and M1, Adeline has seen what happens when organizations ask teams to move faster, adopt new technology, and compete in changing markets without giving people the safety, clarity, and confidence to do their best work. She helps leaders find the sweet spot between high performance and psychological safety, where teams can deliver results while still feeling empowered to speak up, innovate, and take risks.

Her approach is practical and evidence-based. Rather than treating leadership development as a one-off event, she designs stackable, scalable, and sustainable learning journeys that build over time. Through her REINVENT™ methodology, set out in her book Reinvent 4.
