Time to face the facts

The hidden costs hitting your hiring right now

Here's a question: how much is unconscious bias costing your organisation this year?

If you're like most hiring teams, you might not have a clear answer. But the research tells a sobering story for UK businesses:

✗ 73% of UK hiring managers admit to making gut-based decisions (CIPD, 2023)

✗ Companies with diverse leadership teams are 25% more likely to outperform competitors (McKinsey Europe, 2024)

✗ The average cost of a bad hire in the UK is £132,000 (CareerBuilder UK, 2023)

✗ 84% of UK organisations believe unconscious bias affects their hiring decisions (Equality and Human Rights Commission, 2023)

But what does bias actually look like in your daily hiring? You probably recognise these scenarios:

  • The "culture fit" excuse: Rejecting qualified candidates because they don't "feel right"
  • The Russell Group bias: Over-weighting university prestige versus actual capability
  • The London postcode effect: Assuming candidates from certain areas lack professionalism
  • The interview inconsistency: Different standards for different candidates

The frustrating part? Most of this happens unconsciously. Your team aren't trying to be biased - they're making quick decisions under pressure.

The solution isn't to eliminate bias from people (impossible), but to build systems that protect candidates from the effects of bias.

Video summary: Business psychologist Ben Schwencke explains five research-backed strategies to reduce bias and build fairer hiring processes.

Let's dive into the five proven steps that actually work...

Step one

Build your bias defense system

Think of unconscious bias like a virus. You can't eliminate it completely, but you can build immunity and install protective measures.

Your two-pronged defence strategy:

Build awareness (but don't rely on it)

Start with education. Help your team recognise common biases like the halo effect, confirmation bias, and affinity bias. But keep expectations realistic - bias training raises awareness without rewiring brains overnight.

Install bias buffers (your real protection)

Instead of hoping people won't be biased, create systems that minimise bias impact:

  • Implement blind CV screening: Remove names, photos, and university details from initial reviews
  • Standardise interview questions: Ask every candidate the same core questions in the same order
  • Use multiple assessors: Never let one person make solo hiring decisions
  • Score independently: Have interviewers complete evaluations before discussing candidates

The key insight? Bias protection works best when it's automatic, not when it relies on people remembering to be fair.

Pro tip: Test Partnership's assessments automatically remove personal identifiers during evaluation, giving you bias-free candidate insights from day one.

Step two

Eliminate systemic bias from your assessments

Even if your team becomes perfectly unbiased (spoiler: they won't), your assessment tools might still be systematically excluding great candidates.

This is called adverse impact - when an assessment produces significantly different outcomes for different groups, regardless of actual job performance potential.

How to spot adverse impact

Watch for these warning signs: gender gaps in scoring, over-indexing on university prestige, cultural bias in questions, or accessibility issues that disadvantage certain candidates.

Your bias audit checklist: Track pass rates by demographics, review job requirements for actual relevance, demand technical manuals from assessment providers, and monitor results quarterly.

Choose bias-resistant assessment types

Not all assessments carry equal bias risk:

Assessment TypeBias RiskWhy It Matters
Personality AssessmentsLowMeasure behavioural traits consistent across groups
Situational Judgement TestsLowFocus on workplace decision-making, not learned knowledge
Skills SimulationsMediumJob-relevant but may reflect training opportunities
Cognitive Ability TestsHigherCan reflect educational background differences
Knowledge TestsHighestStrongly influenced by educational and cultural background

Focus on personality and behavioural assessments for early-stage screening, then use targeted skill assessments only when directly job-relevant.

Smart strategy: Our personality assessments are specifically designed to minimise adverse impact while maximising predictive accuracy.

Step three

Remove accessibility barriers before they exclude talent

Accessibility bias affects 15% of the UK population (Office for National Statistics, 2023) and it's often completely avoidable. You might find the perfect candidate who can't complete your assessment because your platform doesn't work with screen readers.

Make accommodations proactive, not reactive

Don't wait for candidates to request accommodations. Build accessibility into your process from the start.

Essential actions: Ensure screen reader compatibility, offer extended time automatically, provide multiple formats (written, audio, large print), test with assistive technologies, and train your team on accommodation requests.

Questions for your assessment provider

Before choosing assessment tools, verify: WCAG 2.1 compliance, screen reader testing, accommodation turnaround times, and accessibility documentation.

Test Partnership advantage: All our assessments are built with accessibility in mind, including WCAG 2.1 compliance and comprehensive accommodation options.

Step four

Build trust through exceptional candidate experience

Here's what most hiring teams don't realise: candidates from underrepresented groups are more likely to interpret negative experiences as signs of systemic bias. When your process feels unfair, diverse candidates drop out at higher rates.

Create inclusive experiences that retain diverse talent

Transparent communication: Set clear expectations about timing, explain why you use assessments, provide progress updates, and offer meaningful feedback regardless of outcome.

Respect and dignity: Respond to applications within 48 hours, personalise communications, ask thoughtful questions about career goals, and keep assessments as short as possible while maintaining validity.

The diversity retention effect

When you create genuinely inclusive experiences, diverse candidates don't just complete your process - they actively advocate for your company, referring other talented candidates from their networks.

Real impact: Our clients report that improving candidate experience increased diverse applicant completion rates by an average of 23%.

Step five

Future-proof your hiring with modern assessment technology

Innovative assessment technologies are specifically designed to minimise bias while maximising candidate engagement. Here are the breakthrough technologies transforming fair hiring:

Adaptive testing that meets candidates where they are

Computer Adaptive Testing (CAT) adjusts question difficulty in real-time. This eliminates frustration, reduces dropout, maximises accuracy, and levels playing fields by giving every candidate questions matched to their ability level.

Game-based assessments that engage diverse candidates

Gamified assessments are mobile-optimised, reduce reading burden, offer cultural neutrality, and create lower-stress experiences for all candidates.

Advanced bias detection technology

Differential Item Functioning (DIF) identifies and eliminates biased questions at the individual item level, ensuring questions work fairly across different demographic groups.

Customised assessments that measure what matters

Bespoke assessments aligned to your competency frameworks eliminate irrelevant factors that introduce bias, focusing only on job-relevant traits.

Innovation advantage: Test Partnership incorporates all these bias-reduction technologies as standard, giving you access to the most advanced fair hiring tools available.

Your next steps

Start immediately: Implement blind CV screening and standardised questions this week. Plan ahead: Research bias-resistant assessment providers and track your diversity metrics. Transform completely: Schedule a platform demo to see exactly how modern assessment technology eliminates bias.

Remember: Reducing bias isn't a one-time project - it's an ongoing commitment to fair hiring. The tools you implement today will continue protecting candidates and improving your hiring quality for years to come.
