If you ever wondered about EADM’s mission

The purpose of the Association is the advancement and diffusion of knowledge about human judgement and decision making and providing support for the exchange of information relating to this subject between the members and other associations throughout the world, as well as between members and other interested institutions and/or individuals. The Association is a non-profit organisation made up of interested researchers.

The Association aims to reach the goals mentioned above by:

  • the organisation and/or facilitation of meetings, workshops, summer-schools and conferences.
  • the promotion of scientific communication and research collaboration between members and between members and other scientists, policy makers, practitioners, and stakeholders.
  • the promotion of all (lawful) activities among members to help advise non-members (institutions and individuals) in accordance with the main goals of the Association.
  • co-operation with other associations and institutions within and outside Europe.

The specific activities of the EADM are:

  • the organisation of biannual conferences on Subjective Probability, Utility and Decision Making (SPUDM).
  • sponsoring the de Finetti Prize for promising PhD students.
  • sponsoring the Jane Beattie mid-career award in recognition of “innovation in decision research”, as broadly understood.
  • sponsoring the Wagenaar Award for travel to SPUDM
  • sponsoring the EADM/SJDM Jane Beattie travel award for travel to the SJDM annual conference.
  • supporting small-scale workshops.
  • organizing a bi-annual Summer-school on judgment and decision-making.
  • maintaining an electronic mailing list for EADM members.
  • maintaining a website featuring news and information for members and non-members
  • supporting the open access scientific journal Judgment and Decision Making, the journal of the Society for Judgment and Decision Making (SJDM) and the European Association for Decision Making (EADM).

The EADM Interview: Dirk Wulff


1) Who are you, and what do you do?

My name is Dirk Wulff. I am a PostDoc at the Center for Adaptive Rationality at the Max Planck Institute of Human Development. I study experience-based decision making and semantic memory.

Within experienced-based decision making I focus quite a bit on exploration and information search. One aspect I am currently interested in is the impact of different stopping rules on the experiences that we make. We all know the problem of assessing the result of an experiment sample-by-sample. The same problem pertains to experience-based decision making. When we explore multiple options before making a choice, a stopping rule that is based on the perceived difference between the options will make the option appear more distinct then they actually are. What we experience can thus be influenced by what we wanted to experience.

Although I work mainly on decision making, I originally moved into research for my fascination with the study of semantic memory. Therefore, I feel lucky to be collaborating on a number of projects on the organization of semantic memory across the lifespan. One project that I find particularly cool is smallworldofwords.com. In this project researchers from many countries work together to obtain human-generated semantic networks for all words in 8 different languages. I help running the German version.

2) What do you consider your most important research tool(s) on your computer?

Hands down R. You have a new idea and you don’t know how it pans out – simulate it with R. You have a theory and you don’t whether it fits the data – model it with R. You have a nice result and want to show it exactly as you want to – plot it with R (base, not ggplot2). Writing code may actually be my favorite part of doing research – I mean aside from getting up late and coffee breaks – and R is perfect for it. Some time ago I also started using Python for natural language processing. The syntax is much more simple and elegant. Everything around the language, e.g., packages or available IDEs, is however nowhere near the convenience of using R (and RStudio).

3) What do you consider your most important research tool(s) outside of your computer?

A café. For some reason my mind is clearest, when working in my favorite café surrounded by chatting strangers. I sometimes joke that this is, because it lets me feel that I have a live outside of academia. The more likely reason however is: there is no Internet.

4) What is your favorite tip for getting writing done?

Force yourself. Or have someone else force you. Still desperately looking for alternative solutions.

The EADM Interview: Peter Wakker


1) Who are you, and what do you do?

I am the grandson of

I will convert all of mankind, including all statisticians, to Bayesianism.
I will introduce the idea of conservation of influence.

2) What do you consider your most important research tool(s) on your computer?  Delete-key.

3) What do you consider your most important research tool(s) outside of your computer?

4)  What is your favorite tip for getting writing done?
Do not force yourself to write; it will not work.
Only forbid yourself to do anything other than writing.

Peter’s CV

The best paper that I ever co-authored was
Abdellaoui, Mohammed & Peter P. Wakker (2005). The Likelihood Method for Decision under Uncertainty. Theory and Decision, 58, 3–76.

It is also my least-cited paper. Explanation (to console myself): In those days the journal printed half per page what other journals did.  In another journal the paper would have taken 37 pages not 74.  No-one prints 74 pages for one paper.

The EADM Interview: Bettina von Helversen

BettinavHelversen1)    Who are you, and what do you do?

I’m a researcher at Basel University working at the Center for Economic Psychology. I investigate the cognitive processes underlying judgments and decisions and how they are shaped by the characteristics of the task and the abilities of the decision maker. A large part of my work focuses on when people rely on rule- and exemplar-based processing in judgment and understanding the memory processes underlying these processes. One project I’m currently working on aims on trying to understand when memories about previously encountered instances are likely to influence the decision process and how this depends on affective experiences when encountering the exemplars. In addition I’m interested in how and when people search for information and how this in influenced by affect and stress.

2)    What do you consider your most important research tool(s) on your computer?

After reading that question I got curious which programs I’m actually using on a daily basis and I downloaded an app that allowed me to track the programs I’m using (TimeSink). A one week trial run suggested that I used the following programs in order of frequency: Firefox, Mail, Word, Powerpoint, Preview (a pdf viewer), Mendeley, Excel, Skype, SPSS and Matlab. Overall, that seems about right, although the order probably changes quite a bit with the projects I’m working on and the amount of teaching I’m preparing. Taking office for granted, I could not imagine doing research without Mendeley, Skype or Matlab anymore.

3)    What do you consider your most important research tool(s) outside of your computer?

Well there is of course the lab without which I would not have much data, but even more important are the people I work with (though they are no tools). For me research works best as a collaborative effort in a team of two to three people.

4)    What is your favorite tip for getting writing done?

I have to admit I’m struggling quite a bit with writing. To get writing done I need to find a day without meetings and preferably no evening plans that allow me an early escape.Additionally, I can recommend fast working coauthors. The knowledge that someone is waiting usually gets me to get my part done much faster and it works even better if the other person was really fast in doing their part.
