Your Go-to Guide for Smarter Judgement
"This is a misjudgement masterclass for decision-makers in high-stakes situations - it not only explains your past mistakes but prevents future ones ..."
We live in a noisy world where the risk of tuning out what really matters is rising - and amplifying error.
When you tune out, you lose out. But when you tune in, you win - and so do those around you.
The most underestimated risk is not necessarily political, economic or climate risk - it's human decision risk - ignored by many until it's too late.
Tune In stands apart. Original and timely, it draws attention to decision “deaf spots,” the judgement killers that stop us from hearing what really matters.
Tune In is timely - never before have people felt more and more unheard, countries are polarised, customers are defecting, employees are revolting with trust and judgement is at an all-time low.
Tune In blends science with entertainment - illustrated by a cast of unforgettable Wall Street titans, sports icons, entrepreneurs, presidents, FBI investigators and moon-landing astronauts.
It introduces new concepts such as the "trilogy of error™" and offers a proprietary framework for misjudgement, underpinned by 75 biases.
The PERIMETERS™ model evaluates how well we tunes in - or out - critical voices based on ten different drivers - Power, Ego, Risk, Identity, Memory, Ethics, Time, Emotion, Relationships and Stories.
Stand out, don't miss out. It's time to become an influential Decision Ninja.
It's time to Tune In.
