On 26 September 2023, Émile Servan-Schreiber shared a recap of his presentation at Luminus. His accompanying message offered a simple instruction: seek out other people’s thoughts and include them in your own thinking. It was a compact account of collective intelligence, addressed to a workplace rather than a forecasting tournament.
The reshared account came from Grégoire Dallemagne. He described diversity and inclusion as a moral imperative and a priority at Luminus, and thanked Servan-Schreiber for explaining how diversity could make people smarter. He also thanked Adrien Marchitelli and Katleen Daems for organising the presentation. His account connects the presentation with Luminus’s stated inclusion priorities.
A documented part of the inclusion programme
Luminus’s 2023 sustainability report independently confirms a conference by Servan-Schreiber on diversity in the service of collective intelligence, intended for members of its leadership. On printed page 89, the company lists it alongside workshops on inclusive culture and recruitment, training on unconscious bias, and other activities addressing workplace inclusion.
The report also describes volunteer employee groups, called Lumiforces, meeting three times during 2023 to help define the company’s inclusion priorities for 2024. The broader programme therefore included a route for employees to help shape an agenda, as well as training for leaders. The company describes the groups as part of its wider inclusion programme, alongside the leadership conference.
What it means to include a different judgement
The forecasting relevance lies in the speaker’s instruction to bring others’ thinking into one’s own. Seeking a second perspective can expose an assumption that a single decision-maker has left unexamined. Turning that practice into a forecast requires a further step: an explicit question and a method for combining judgements. That moves the discussion from inviting contributions to deciding how they will inform a shared answer.
The journal’s discussion of expertise and diversity in collective intelligence develops that methodological question. At Luminus, leaders heard the case for seeking different perspectives, while volunteer employee groups contributed to the inclusion agenda. The two activities address different stages of collective work: making room for contributions and using them to set priorities.
