Interview with Thomas Sturm on the Science of Rationality and the Rationality of Science

In this post I am pleased to interview Thomas Sturm (pictured below), ICREA Research Professor at the Department of Philosophy at the Universitat Autónoma de Barcelona (UAB) and member of the UAB's Center for History of Science (CEHIC). His research centers on the relation between philosophy and psychology, including their history. Here, we discuss his views on empirical research on human rationality.

AP: The psychology of judgment and decision-making has been divided into what appear to be radically different perspectives on human rationality. Whilst research programs like heuristics and biases have been associated with a rather bleak picture of human rationality, Gerd Gigerenzer and his colleagues have argued that very simple heuristics can make us smart. Yet, some philosophers have also argued that, upon close scrutiny, these research programs do not share any real disagreement. What is your take on the so-called “rationality wars” in psychology?

TS: Let me begin with a terminological remark. I would like to refrain from further using the terminology of “rationality wars”. It was introduced by Richard Samuels, Stephen Stich, and Michael Bishop (SSB hereafter) in 2002, and I have used their expression too without criticizing it. In academic circles, we may think that such language creates no problems, and I hate to spoil the fun. But because theories of rationality have such a broad significance in science and society, there is a responsibility to educate the public, and not to hype things. Researchers are not at war with one another. Insofar as a dispute becomes heated, if fights for funding and recognition play a role, then we should speak openly about this, tame down our language, and not create a show or a hype. We should discuss matters clearly and critically, end of story.

Now, I study this debate, which has many aspects, with fascination. It’s fascinating because they concern a most important concept of science and social life, adding fresh perspectives to philosophical debates that have occasionally become too sterile. And the debates are so interesting because they provide ample materials for philosophy of science.

Strategic Thinking, Theory of Mind, and Autism

My name is Peter Pantelis. I study “theory of mind”—our ability to reason about other people’s mental states. Years ago, I became interested in an economic game called the Beauty Contest, because I think it taps into theory of mind very elegantly:

You are going to play a game (against 250 undergraduate psychology students). Each player will submit a whole number from 0 to 100. The winner will be the player whose number is closest to 2/3 of the mean number selected by all the players.

What number do you submit?

(I’ll wait for you to think about it for a moment)

Memories: Distorted, Reconstructed, Experiential and Shared

PERFECT 2017 Memory Workshop

We are very excited that on 5th May 2017 Project PERFECT will be holding its second annual workshop, at Jesus College, Cambridge. The workshop will feature leading experts in the field of philosophy of memory. The talks will focus on a wide-range of fascinating issues that dominate contemporary research on memory. The talks will be of interest to philosophers of mind, philosophers of psychology, epistemologists and psychologists, as well as other cognitive scientists interested in how we remember the past.  

Issues to be covered in the talks include how memory can generate knowledge; how false and distorted memories can be useful features of ordinary cognition; the nature of experiential memories; whether we can be immune from error due to misidentifying ourselves in a memory; and the role of shared memories in relationships. 

Many of the talks will have an interdisciplinary angle, highlighting how recent psychological research—e.g. on false and distorted memory, and dementia and grief—should impact on our understanding of human memory.

Two of the talks will focus directly on a concept at the very heart of Project PERFECT: i.e. epistemic innocence. This is the idea that some false and misleading cognitions bring epistemic benefits that could not be possessed in the absence of the cognitions.

Kirk Michaelian will examine the claim that memory can generate new knowledge. He will explore two views that are consistent with this claim, arguing that the views, when combined, support the claim that episodic memories (our memories of individual incidents) are misleading but in a way that makes them epistemically innocent.

On a similar theme, I will present work written in collaboration with Lisa Bortolotti showing that three memory distortions famously studied in the psychological literature can be explained in terms of the presence of cognitive mechanisms that are epistemically innocent.

Dorothea Debus will explore the nature of memories with experiential qualities. She will argue that we give this type of memory special weight, and she will illustrate how we are both passive and active with respect to these memories. We are active because we can prompt ourselves and others to remember events. We are passive because the memories often just come to us.

Jordi Fernández will examine the claim that one cannot have an inaccurate memory as a result of misidentifying oneself in the memory. He will consider how psychological research on observer memories (when people seem to recall a scene in which they featured from the perspective of an observer) and disowned memory might be taken to challenge the claim. Then he will respond to the challenge by drawing on the same psychological research to offer a positive view in support of the target claim.

John Sutton will focus on how the ways people have shared memories that are reflected in and can come to constitute specific close relationships. He will focus on both ongoing relationships and the end of relationships. He will draw on psychological studies on the role of memory in dementia and grief.

Bounded Rationality Meets Situated and Embodied Cognition

This post is by Enrico Petracca (University of Bologna), who recently published a paper entitled ‘A cognition paradigm clash: Simon, situated cognition and theinterpretation of bounded rationality’ in the Journal of Economic Methodology. Enrico is involved in a project called ‘embodied rationality’, and pursued with his colleague Antonio Mastrogiorgio (University of Chieti-Pescara). The project aims to integrate the notion of embodied cognition within the framework of bounded rationality.

Bounded rationality has been a hard-to-digest notion in economics and the other social sciences since its introduction by Herbert A. Simon in the middle of the last century. How could ‘rationality’ be ‘bounded’? And – as a typically related concern – would this imply that social sciences should abandon any normative horizon, giving the way to an unappealable ‘irrationality’?
