do not believe everything

Behavioral Psychologist (PhD)
About me
Hi, I am Nika and I am a born behavioural scientist. I needed to be one, because I was too late when the “manual of life” was handed out. I didn’t understand why I seemed to fit in, but it never really felt that way.
So, I kept wondering.
After 15+ years in corporate environments and a PhD in Behavioural Psychology, I discovered that the gap between how systems work and how people feel inside them is not a personal failure. It’s structural.
The same biases that keep organisations frozen in yesterday are the ones that make individuals feel broken for not fitting in. The KPI reflex, the objectivity illusion, the one-size-fits-all myth … these are not just corporate problems. They shape how we think about ourselves.
I started with ADHD. My own late diagnosis at 39 taught me that the “deficit” in “Attention Deficit” says more about the system’s metrics than about the people it measures. A penguin won’t fly, no matter how many remedial lessons she receives. But in water, she’s extraordinary.
Status-Quo-Intolerant
That insight opened a door. The further I looked, the more structural biases I found. In hiring, in leadership, in decision culture, in the stories we tell ourselves about who belongs and who doesn’t.
GuerillaBrain is where I translate these patterns. For the leaders who steer the system and sense it’s not working. And for the people living inside it who sense something is off but can’t name it.
No templates. No how-tos. No 5-step plans.
Instead: a mirror and a language for what has been feeling wrong.

What I Do
SCIENCE COMMUNICATION
I decode structural biases at the intersection of behavioural psychology, decision culture, and neurodiversity.
WRITING
Regular essays, research translations, and the occasional fairy tale … on Substack (DE) and LinkedIn (EN).
SPEAKING
Keynotes, panels, podcasts, and lectures on cognitive biases, decision culture, and why organisations keep rewarding yesterday’s behaviour.
