All this began with my whistleblowing on research misconduct by Hülsheger, Derous, Lang/Ippolito, Fontaine & Zijlstra.
My paper “Science Eroded” documents the evidence and the institutional retailation that followed — and I submitted it to all these conferences.

It’s not easy to face these renewed attempts at exclusion — but I’m not discouraged and look forward to #INFORMS2025 with optimism and resolve. Research misconduct and “exception policies” to avoid scrutiny must stop. ✨🌿

My letters (Aug 15, Aug 19, Sept 15 2025) reminded INFORMS that only the Board, by a two-thirds vote, can impose sanctions — and only after written charges, full evidence, and a fair hearing (audi alteram partem). That’s how integrity works. 📚

well Blechert wrote that he tried to find a compromise... there is no half lawfully present or something like that. Also police did not intervene. The whole thing was unlawful from the start...

When I tried to report the misconduct, I was arrested 2x at a German psychology conference ( @dgps.bsky.social ) after false info was given to the police in NRW (where my ex-wife works). This investigation has luckily recently been dismissed (meaning wrongful detention!).

In contrast, I immediately faced a criminal case when I stopped paying support after the €100,000 “gift” claim — when I was:
❌ denied all contact with my children,
❌ pressured to keep doing scientific work for my ex-wife,
❌ children were told my father + ex-wife were “their parents.”

(a) I barely earn anymore and hardly survive financially
(b) My daughter lived with me for parts of that time.
Still, money was taken.
