Which Recruiting Methods Actually Work?
An interactive overview of how well different selection methods predict performance, based on the largest meta-analysis of the past 30 years. Structured interviews clearly beat IQ tests.

Perspective · Hiring & Leadership
How to Spot a Toxic Leader Before You Hire Them
People with toxic behavior patterns often make the strongest impression in interviews. Why that happens, and how to check for it systematically (Reynolds & Rogelberg, 2026).

Perspective · Leadership & Decisions
Relationship First, Then Feedback: Why Harsh Feedback Rarely Improves Performance
Positive feedback reliably improves performance. Negative feedback does not — it depends on the relationship. Why leadership often does the wrong thing under pressure (Heine, Stouten & Liden, 2026).

What Happens When Strangers Ask Honest Questions: A Living Library on ADHD
A day as a "book" at a Living Library. On honest curiosity from strangers, vulnerability — and what it has to do with professional practice.

AI at Work: Relief or Burden? What Job Design Decides
The same AI can relieve one team and burden another. The difference isn't the tool, but two questions: choice and collaboration (Bakker et al., 2026).

Perspective · Leadership & Decisions
The Hidden Profile Problem: Why Teams Don't Share Their Most Important Knowledge
Groups prefer to discuss what everyone already knows. What only one person knows often stays hidden — even in good teams (Stasser & Titus, 1985). Why this happens, and what two countermeasures achieve.

Perspective · Selection
Likeability or Competence? Why Selection Needs Both
"He just fits us better." Likeability is not a bad signal, it is simply rarely matched by an equally rigorous test of competence. Teams built on only one of the two break at the same point (Chen et al., 2026). Three steps that make the difference.

Research · Team & Organization
Workplace Bullying: Who Leaves — and Who Stays
Five years after bullying, it's disproportionately the targets who are gone — the perpetrators are still there (Glambek et al.). Why organizations lose the wrong people, what it costs, and three levers that change the process.

Feature · Neurodiversity & Leadership
70% Readiness, 35% Trust: The Gap Almost Nobody Measures
Employers rate their organization as ready (70 to 75 percent). Only 32 to 38 percent of neurodivergent employees feel safe enough to disclose (City & Guilds Foundation, Neurodiversity Index 2026). Why the gap is not about attitude, but about process.

Perspective · Leadership
Bad Leadership Rarely Comes from Bad People
It comes from pressure, often self-made. From a PhD leadership course at UZH: four levers that make the difference, catch anger early, show direction, let people grow, and stop sitting on things.

Article · Neurodiversity & HR
Neurodiversity across the whole employee lifecycle: why hiring is only the start
Neurodivergent people are roughly 8× more likely to be unemployed (Volpone & Hennekam, 2026). A systematic review of 244 studies shows the problem doesn't sit in recruiting alone, it runs across the entire employee lifecycle, from onboarding to retention. What that means for Swiss organizations.

Article · AI & Hiring
Disability Bias: How AI Screening Filters Out Neurodivergent Talent
AI tools rate résumés that mention a disability lower, even when they're objectively better (Glazko et al., 2024). Hit hardest: autism and deafness. What it means for Swiss organizations, and why structured selection protects you.

Perspective · ADHD & Neurodiversity
Disorder or Natural Variation? Why ADHD Is Both
A professor just said "variation", and moved on. Why ADHD is at once a clinical disorder and a natural human variation (Faraone et al., 2024; Sonuga-Barke et al., 2023), and why at work it's not the label that counts, but the fit.

Article · Behavior Change
Change That Lasts: Why Initiatives Fizzle, and What Makes Them Stick
Changing attitudes isn't enough, the intention-behavior gap sits in between. What the COM-B model (Capability × Opportunity × Motivation) means for leadership and organizational development in Swiss organizations, and why change so often fizzles out day to day.

Perspective · ADHD & Self-Employment
ADHD and Self-Employment: It's Not the Person, It's the Environment
A new meta-analysis (Tran et al., 2025) shows: ADHD drives entrepreneurial behavior, but guarantees no success. The environment decides that. Why neurodivergent talent leaves companies, and what it costs Swiss organizations.

Article · Recruiting & Precision
Hire on Target: Win the 15% of Talent Standard Recruiting Loses
ADHD, autism, dyslexia, 15-20% of the working population is neurodivergent. Your recruiting process filters them out before you ever see their potential. What it costs, and how three adjustments make the difference.

Whitepaper · ADHD in the Workplace
From Friction to Performer: What ADHD Really Delivers on a Team
An original empirical study with 24 interviews shows: when those affected help develop the tool, empathy improves measurably (Wilcoxon p = .016, r = .89). What this means for recruiting, leadership, and teamwork in Swiss organizations, including three ADHD-specific takeaways for tomorrow.
