In 2020, I was sitting in a boardroom when I watched psychological safety fail in real time. The mining company’s head of operations had just spent 15 minutes explaining how their new safety protocols weren’t gaining traction with frontline workers. A junior engineer raised her hand – she felt safe enough to speak up, just as all those expensive psychological safety workshops had trained her to do.

‘The protocols don’t account for equipment variations between sites,’ she said. ‘The frontline teams are adapting them anyway, but we’re not capturing their innovations.’

Silence. Then the conversation moved on. She had been psychologically safe to speak, but her contribution was completely ignored. I watched her shoulders drop. That moment wasted her time and focus, and ultimately cost the company performance that could have been avoided.

In 2021, companies are wasting millions on psychological safety initiatives that miss four-fifths of what actually drives [workplace belonging](https://www.sovereignmagazine.com/article/why-the-health-culture-crisis-shows-businesses-need-better-employee-feedback-systems).

## **The Costly Mistake Companies Keep Making**

[After working with close to 200,000 employees](https://belongingfirst.com/research-and-media/), I found something that should concern every executive writing cheques for workplace culture initiatives: psychological safety is just one of five measurable belonging indicators. Companies focus obsessively on this single metric while completely ignoring comfort, connection, contribution and wellbeing.

Global employee disengagement costs [$8.8 trillion annually](https://www.gallup.com/workplace/393497/world-trillion-workplace-problem.aspx), yet companies continue throwing money at the wrong solutions. Up until 2025, in the US alone, companies were spending roughly [$8 billion annually](https://www.inspireinvesting.com/post/inspire-mobilizes-investors-to-urge-fortune-1000-companies-to-avoid-dangerous-dei-policies) on DEI efforts, with Fortune 1000 businesses averaging $1.5 million each on diversity budgets.

When belonging is compromised across multiple indicators, task completion drops by 42%. That junior engineer in the boardroom? Her mental energy was being drained not because she felt unsafe to speak, but because her contributions weren’t valued, her connection to decision-makers was weak and her wellbeing was compromised by feeling invisible.

## **The Hidden Bias Silencing Your Data**

Traditional employee surveys suffer from what I call ‘Outlier Treatment Bias’ – statistical methods that treat marginalised voices as noise rather than signals. When you aggregate survey responses and remove ‘outliers’, you’re often silencing the exact people whose experiences reveal systemic problems.

I found this during my 2021 research [establishing a neuroscience-based framework for belonging](https://adleruniversity.academia.edu/AndreaCarter). Standard survey analysis flagged responses from women and visible minorities as statistical outliers because their experiences differed significantly from the majority. But these weren’t outliers – they were early warning signals of cultural breakdown. More effective feedback systems are emerging that capture these crucial perspectives instead of discarding them.

The neuroscience supports this. When people don’t belong, their brain’s stress response hijacks cognitive resources needed for collaboration. Chronic stress sends immune cells to the brain, literally changing how we process information and contribute to our teams.

This is why belonging drives performance by regulating [stress response](https://www.sovereignmagazine.com/article/kintsugi-a-metaphor-for-healing-in-a-fragmented-world). Companies measuring only psychological safety are missing four-fifths of the brain processes that enable peak performance.

## **Real Costs, Real Solutions**

I worked with a manufacturing client last year whose production errors dropped 18% and contribution scores rose 22% after implementing measurements across all five belonging indicators. Instead of asking workers if they felt ‘safe to speak up’, we measured whether they felt comfortable in their physical workspace, connected to colleagues and leadership, valued for their unique contributions, psychologically safe to take risks and supported in their overall wellbeing.

The contrast with current industry struggles is stark. Despite massive investments in psychological safety training, only 21% of employees globally are engaged, and 24% of corporate training budgets still go to [DEI initiatives that aren’t moving the needle](https://www.sovereignmagazine.com/article/when-training-becomes-the-target-how-mandatory-workplace-programmes-face-growing-legal-scruti) on actual inclusion.

Companies focusing solely on psychological safety are like builders who only check if the foundation is [level while ignoring whether it’s strong enough](https://www.sovereignmagazine.com/article/the-2-trillion-communication-crisis-ruining-everything-from-boardrooms-to-family-dinners) to hold the building. You can speak up all you want, but if your contributions aren’t valued, your connections are weak and your wellbeing is compromised, that foundation will still crack under pressure.

My manufacturing client saw immediate results because we addressed belonging as systems, not as a nice-to-have cultural add-on. Workers weren’t just safe to speak – they were comfortable, connected, valued and supported. Supporting employee wellbeing in practical ways improved performance that psychological safety training alone never achieved.

## **The 50/50 Accountability Model**

Traditional belonging initiatives put 100% of the responsibility on employees to ‘fit in’, which drains mental energy and erases contribution. I developed what I call the [50/50 accountability model](https://www.sovereignmagazine.com/article/the-business-of-talent-learning-development-is-learning-finally-prove-its-worth): employees bring their authentic selves and unique perspectives, while organisations create the support for those contributions to be valued.

Instead of asking employees ‘How can you better integrate into our culture?’, leaders ask ‘What support do you need to contribute your best work?’ Instead of requesting updates, they inquire about obstacles. Instead of expecting adaptation, they design inclusion.

I watched this change at a tech company where managers shifted from weekly status meetings to monthly problem-solving conversations. Employee contribution scores increased by 31% within six months, and voluntary turnover among underrepresented groups dropped by 45%.

The research on mental strain supports this approach. When employees spend mental energy trying to fit in rather than contribute, you lose problem-solving capacity and the diverse thinking that drives results. Companies tracking belonging alongside engagement see higher retention rates and improved financial performance.

Leaders implementing the 50/50 model stop asking their people to contort themselves into existing systems and start designing systems that support everyone’s potential. That’s not cultural sensitivity – that’s business intelligence.

## **Beyond Compliance to Culture Change**

Recent research reveals that 60% of companies lack dedicated DEI roles, highlighting how belonging initiatives often lack proper support. Meanwhile, one in eight companies plan to reduce or eliminate DEI programmes in 2025, citing lack of measurable ROI.

Companies abandoning DEIwork aren’t wrong about the ROI problem – they’re just measuring the wrong things. Psychological safety workshops don’t deliver measurable business impact because they address symptoms, not systems. My research provides a framework for organisations serious about moving beyond compliance theatre.

Belonging isn’t a perk that makes employees feel good. It’s the foundation that enables retention and trust. When you measure and [optimise across all five indicators](https://theconversation.com/in-the-face-of-dei-backlash-belonging-plays-a-key-role-to-future-success-230289) – comfort, connection, contribution, psychological safety and wellbeing – you create conditions where diverse perspectives drive business results rather than just demographic representation.

The research and tactical applications that came from my comprehensive mining belonging study led to working with companies that saw an average productivity increase of 23% and new business growth of 34%. They didn’t spend more money – they spent it more intelligently, addressing the full spectrum of what makes humans thrive at work. The business case for genuine inclusion becomes clear when you measure what actually matters.

As global disengagement costs continue climbing toward $9 trillion annually, companies can’t afford to keep treating belonging as an HR nice-to-have. Organisations implementing comprehensive inclusion strategies see measurable returns on investment because they’re building support systems, not running workshops.

Companies that will succeed are those that understand belonging isn’t about making everyone comfortable – it’s about creating conditions where everyone can [contribute their best thinking](https://www.sovereignmagazine.com/article/real-conversations-real-impact-shaping-the-next-generation-of-leaders) to solving complex problems. That’s not diversity training. That’s how you stay ahead of the competition.
