A 50-Year History of Business Psychology: Fairness, Practice, and Professional Identity
Prologue
Before this timeline starts in 1975, workplace psychology and psychometrics were well established.
-
Early 1900s: Münsterberg linked psychology to work. Hugo Münsterberg (1913) applied psychology to industrial efficiency.
-
1910s–40s: The UK Army Alpha and Beta tests were used in World War I, and the British War Office Selection Boards in the 1940s demonstrated the power of large-scale testing and assessment centres. This demonstrated mass assessment and assessment centre roots.
-
1950s–70s: The National Institute of Industrial Psychology (NIIP) in the UK, along with influential tools such as Cattell’s 16PF and the adoption of assessment centres by AT&T in the 1950s, helped shape modern occupational testing and demonstrate Business Psychology becoming more mainstream with professionalisation.
-
By the 1960s and 70s, occupational psychology had an established academic and professional footing, with psychometrics for specialists, complex in design, and derived from clinical roots.
1975–1989 | From Psychometrics to Organisational Impact
Selection and development moved from artisan methods to repeatable, data-driven practice. The profession began to balance academic rigour with applied practice, setting the stage for global recognition.
-
1977–mid-1980s: The founding of SHL by Peter Saville & Roger Holdsworth, and the launch of the Occupational Personality Questionnaire (OPQ) made workplace assessment business-focused, user-friendly, and scalable beyond academia and clinical settings. This democratising of assessment for HR professionals was influential in commercialising and scaling workplace psychometrics, particularly in the UK. That in turn saw more embedding of Business Psychology in organisational life.
-
SIOP (US): The Society for Industrial & Organizational Psychology, originally APA Division 14 (1936), became “SIOP” in 1982, establishing itself as the strongest global scholarly and professional anchor.
-
EAWOP roots: A 1980 European network of researchers and practitioners matured and laid the foundations for what became the European Association of Work & Organisational Psychology (EAWOP) in 1991.
1990–1999 | Professionalisation Across Regions
A recognisable market for Business Psychology emerged. Practitioners became trusted advisers to executives, showing that Business Psychology was not peripheral but central to organisational effectiveness.
-
1991: EAWOP formally founded, cementing a pan-European identity and emphasising scientific foundations and cross-national collaboration.
-
National societies: Bodies in the Netherlands, Greece, and elsewhere integrated W&O psychology into national frameworks, expanding practitioner communities.
-
Boutique consultancies: Firms like YSC (founded 1990), Kiddy & Partners (expanding), and Kaisen grew alongside corporate HR, bringing psychologists into boardrooms and C-suites.
-
Executive coaching: Exploded across disciplines; by 2004, Harvard Business Review called it the “Wild West of Executive Coaching.”
-
1999: The Chartered Institute of Personnel and Development (CIPD) published a “Competencies Handbook”, co-authored by Steve Whiddett and Sarah Hollyforde, which becomes a standard reference in the field.
2000–2009 | Business Psychology Identity, Competencies, and Wellbeing
Business Psychology expanded from hiring into wellbeing, ethics, and organisational culture. A distinct practitioner identity developed, with The ABP providing a home for non-academics and cross-disciplinary professionals.
-
2000: A professional community of Business Psychologists began registering members, which led to the Association of Business Psychologists being legally incorporated on 5 December 2002. (The later name change, on 12 December 2013, to The Association for Business Psychology, signalled inclusion of a broader base of membership and accessibility for non-specialists seeking to use Business Psychology in their organisations.)
-
2004: The UK HSE Management Standards for work-related stress brought psychosocial risk management into mainstream organisational development.
-
2005–2006: The competency movement crystallised with Bartram’s Great Eight and SHL’s Universal Competency Framework, widely adopted in corporate HR.
-
2006: The International Test Commission (ITC) issued guidelines for online and computer-based testing, followed by updates on test use.
-
2009: CIPD launch their Profession Map, setting out the knowledge, behaviours, and values expected of HR and L&D professionals and drawing heavily on psychology-informed principles such as ethical practice, evidence-based decision-making, and inclusive behaviours.
The CIPD Profession Map reinforced the influence of psychological science on mainstream HR standards. It highlighted the importance of having Business Psychologists work alongside HR as partners, ensuring fairness and evidence-based approaches were embedded across people practices. It also provided a shared language of competencies that helped position Business Psychology not as a niche, but as a core contributor to professional people management.
2010–2015 | Consolidation and Analytics Go Mainstream
Business Psychology became embedded inside global advisory and tech ecosystems. Talent, leadership, and analytics became strategic boardroom issues. Fairness and bias in assessment gained renewed focus, while diversity movements (#BlackLivesMatter from 2013) shaped corporate demand for inclusive practices.
-
2011/12: ISO 10667 introduced global standards for assessment service delivery.
-
M&A boom:
• IBM acquired Kenexa (2012, ~$1.3bn).
• CEB acquired SHL (2012, ~$660m).
• Korn Ferry acquired PDI Ninth House (2012–13).
• Deloitte acquired Bersin & Associates (2013).
• Towers Watson acquired Saville Consulting (2015).
-
2013: The ABP name change from “of” to “for” symbolised inclusivity, welcoming those applying psychology in business without requiring formal psychologist status.
-
2013: The Alliance for Organizational Psychology (AOP) founded, uniting SIOP, EAWOP, and CSIOP as a global voice.
-
2014: The ABP Workforce Experience awards created to celebrate excellence in Business Psychology and demonstrate the real-world value of best practice, publishing case studies for global consumption.
-
2015 (31 January): The BPS Division of Occupational Psychology releases The Design and Delivery of Assessment Centres standard, raising the bar for best practices in assessment centre methodology. The ABP had a key role in the working group that developed these standards.
2016–2020 | Platforms, Private Equity, and Scale
Assessment and leadership advisory matured into platform businesses. M&A validated psychology as strategic assets. But integration into corporates risked diluting professional identity, prompting new start-ups to preserve specialisms and culture.
-
2017: Aon acquired cut-e, expanding digital/gamified assessments.
-
2018: Gartner sold SHL to Exponent PE (~$400m), reflecting strong investor confidence in psychometric IP.
-
2018: Gateley acquired Kiddy & Partners, blending leadership psychology into diversified services.
-
2019: The ABP introduced Certification paths for Business Psychologists, offering professionals in the industry an identity and validation of best practice.
-
2019: BIOP (Blacks in I/O Psychology) founded, promoting representation and advocacy for Black practitioners.
-
#MeToo and beyond (2017–19): Inclusion expanded to race, gender, and intersectionality; workplaces faced greater scrutiny of systemic inequities.
2021–2025 | Wellbeing, Regulation, and AI Reshape Practice
The focus shifted from “can we measure it?” to “can we measure it safely, fairly, and with wellbeing in mind?” Standards, governance, and audits are now as central as science. Business Psychology stands as the guarantor of fairness; even as corporate language around EDI ebbs and flows.
-
2020–22: Global surge in EDI initiatives after George Floyd’s death. Bias audits, leadership pipelines, and employee groups became widespread.
-
2021: ISO 45003 published, formalising psychological health & safety at work.
-
2022: Accenture acquired YSC Consulting, integrating leadership boutique expertise.
-
2023: Saville Assessment carved out by Tenzing, highlighting psychometric IP’s standalone value.
-
2023–25: EDI retrenchment: Fortune-100 reduced “DEI” language; firms like Google, Microsoft, and Boeing scaled back DEI teams. Activist-led rollbacks targeted high-profile brands.
-
2024–25: EU AI Act classified HR/assessment AI systems as “high-risk,” demanding transparency, bias control, and human oversight.
-
The ABP launched Guardianship and Growth strategy, demonstrating commitment to accessibility whilst supporting high standards of practice in the industry.
