Random generation is what comes to mind in naturalistic settings
Being unpredictable is useful for creativity, exploration, and good decision-making. Decades of research asking people to generate random sequences of numbers have concluded that people systematically deviate from randomness, but individuals do so in very idiosyncratic ways. However, there is no consensus on the cause of these rich individual differences: most theories postulate that people achieve this by spending cognitive resources monitoring …
Noise in Cognition
Noise in behavior is often considered a nuisance: Although the mind aims for the best possible action, it is let down by unreliability in the sensory and response systems. Researchers often represent noise as additive, Gaussian, and independent. Yet a careful look at behavioral noise reveals a rich structure that defies easy explanation. First, in both perceptual and preferential judgments sensory and response noise may potentially play only mino…

Electrospun radially oriented berberine-PHBV nanofiber dressing patches for accelerating diabetic wound healing
A dressing patch made of radially oriented poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) nanofibers was successfully manufactured with a modified electrospinning strategy. The as-electrospun PHBV radially oriented nanofiber dressing patch exhibited uniform and bead-free nanofibrous morphology and innovative radially oriented arrangement, which was demonstrated to possess obviously improved mechanical property, increased surface hydrophilici…
Contractualist tendencies and reasoning in moral judgment and decision making
The social-contract tradition of Hobbes, Rousseau, Kant, and Rawls has been widely influential in moral philosophy but has until recently received relatively little attention in moral psychology. For contractualist moral theories, ethics is a matter of forming, adhering to, and enforcing (hypothetical) agreements, and morality is fundamentally about acting according to what would be agreed by rational agents. A recent psychological theory, virtua…
When rules are over-ruled
Rules help guide our behavior-particularly in complex social contexts. But rules sometimes give us the "wrong" answer. How do we know when it is okay to break the rules? In this paper, we argue that we sometimes use contractualist (agreement-based) mechanisms to determine when a rule can be broken. Our model draws on a theory of social interactions - "virtual bargaining" - that assumes that actors engage in a simulated bargaining process when nav…
The statistics of cognitive variability
Psychological variability (i.e., "noise") displays interesting structure which is hidden by the common practice of averaging over trials. Interesting noise structure, termed 'stylized facts', is observed in financial markets (i.e., behaviors from many thousands of traders). Here we investigate the parallels between psychological and financial time series. In a series of three experiments (total N = 202), we successively simplified a market-based …
An s-frame agenda for behavioral public policy research
We have previously argued thatbehavioral scientists have been testing and advocating individualistic (i-frame) solutions to policy problems that have systemic (s-frame) causes and require systemic solutions. Here, we consider the implications of adopting an s-frame approach for research. We argue that an s-frame approach will involve addressing different types of questions, which will, in turn, require a different toolbox of research methods
The i-frame and the s-frame
An influential line of thinking in behavioral science, to which the two authors have long subscribed, is that many of society's most pressing problems can be addressed cheaply and effectively at the level of the individual, without modifying the system in which the individual operates. We now believe this was a mistake, along with, we suspect, many colleagues in both the academic and policy communities. Results from such interventions have been d…
The impact of experience on decisions based on pre-choice samples and the face-or-cue hypothesis
Clarifying the relationship between coherence and accuracy in probability judgments
Bayesian approaches presuppose that following the coherence conditions of probability theory makes probabilistic judgments more accurate. But other influential theories claim accurate judgments (with high "ecological rationality") do not need to be coherent. Empirical results support these latter theories, threatening Bayesian models of intelligence; and suggesting, moreover, that "heuristics and biases" research, which focuses on violations of c…
Instantaneous systems of communicative conventions through virtual bargaining
People can instantaneously create novel conventions that link individual communicative signals to meanings, both in experiments and everyday communication. Yet a basic principle of natural communication is that the meaning of a signal typically contrasts with the meanings of alternative signals that were available but not chosen. That is, communicative conventions typically form a system, rather than consisting of isolated signal-meaning pairs. A…
What Does Deliberate Ignorance Reveal to Us About Human Psychology
Deliberate Ignorance is unlikely to be the next book you notice arrayed on custom-made cardboard display racks at the airport, but it arrives at an opportune time. The current challenges of fake news, echo chambers, and conspiracy theories make it particularly urgent to understand the complex ways people interact with information. And if not in airport displays, this provocative set of chapters collected into one volume merits a place on the shel…
What is the point of behavioural public policy? A contractarian approach
Many proponents of behavioural public policy work within a broadly consequentialist framework. From this perspective, the ultimate aim of public policy is to maximise utility, happiness, welfare, the satisfaction of preferences, or similar; and the behavioural aspect of public policy aims to harness a knowledge of human psychology to make this maximisation more effective. In particular, behavioural insights may be crucial to help policy-makers ‘s…

Consensus, cognitive frailty and the limits of the state
From a contractarian perspective, the powers of the state should be underpinned by the agreement of its citizens. But (1) citizens will have inconsistent preferences about the state they want, not just between, but within, individuals; (2) some people may wish to impose rules on others; and (3) citizens may have systematically incorrect models of the consequences of state power. In the light of these challenges, I will ask how far these difficult…
The Fragmentation of Vision
Top-down and bottom-up views of public choice
Frijters et al. make a powerful and lucid case for a top-down approach to government, in which the maximization of wellbeing should be the ultimate goal. I argue, by contrast, for a bottom-up approach: that the variety of goals, plans, norms and rules that govern our lives should be the starting point for political discussion. From this standpoint, the goal of individual and collective decision-making of all kinds is the reconciliation of conflic…

Putting nudges in perspective
Conventional economic policy focuses on ‘economic’ solutions (e.g. taxes, incentives, regulation) to problems caused by market-level factors such as externalities, misaligned incentives and information asymmetries. By contrast, ‘nudges’ provide behavioural solutions to problems that have generally been assumed to originate from limitations in human decision making, such as present bias. While policy-makers have good reason for exploiting the powe…
Towards an integrated science of language
The Now-or-Never bottleneck
Memory is fleeting. New material rapidly obliterates previous material. How, then, can the brain deal successfully with the continual deluge of linguistic input? We argue that, to deal with this “Now-or-Never” bottleneck, the brain must compress and recode linguistic input as rapidly as possible. This observation has strong implications for the nature of language processing: (1) the language system must “eagerly” recode and compress linguistic in…
Implicit learning of non-adjacent dependencies
Language and other higher-cognitive functions require structured sequential behavior including non-adjacent relations. A fundamental question in cognitive science is what computational machinery can support both the learning and representation of such non-adjacencies, and what properties of the input facilitate such processes. Learning experiments using miniature languages with adult and infants have demonstrated the impact of high variability (G…
The under-appreciated drive for sense-making
This paper draws attention to a powerful human motive that has not yet been incorporated into economics: the desire to make sense of our immediate experience, our life, and our world. We propose that evolution has produced a 'drive for sense-making' which motivates people to gather, attend to, and process information in a fashion that augments, and complements, autonomous sense-making. A large fraction of autonomous cognitive processes are devote…
Choice Blindness and Preference Change
Choice blindness is the finding that participants both often fail to notice mismatches between their decisions and the outcome of their choice and, in addition, endorse the opposite of their chosen alternative. But do these preference reversals also carry over to future choices and ratings? To investigate this question, we gave participants the task of choosing which of a pair of faces they found most attractive. Unknown to them, we sometimes use…

New Axioms for Probability and Likelihood Ratio Measures
Probability ratio and likelihood ratio measures of inductive support and related notions have appeared as theoretical tools for probabilistic approaches in the philosophy of science, the psychology of reasoning, and artificial intelligence. In an effort of conceptual clarification, several authors have pursued axiomatic foundations for these two families of measures. Such results have been criticized, however, as relying on unduly demanding or po…
How the Bayesians got their beliefs (and what those beliefs actually are)
Bowers and Davis (2012) criticize Bayesian modelers for telling "just so" stories about cognition and neuroscience. Their criticisms are weakened by not giving an accurate characterization of the motivation behind Bayesian modeling or the ways in which Bayesian models are used and by not evaluating this theoretical framework against specific alternatives. We address these points by clarifying our beliefs about the goals and status of Bayesian mod…

Financial prospect relativity
We report three studies in which methodologies from psychophysics are adapted to investigate context effects on individual financial decision‐making under risk. The aim was to determine how the range and the rank of the options offered as saving amounts and levels of investment risk influence people's decisions about these variables. In the range manipulation, participants were presented with either a full range of choice options or a limited sub…
Human rationality and the psychology of reasoning
British psychologists have been at the forefront of research into human reasoning for 40 years. This article describes some past research milestones within this tradition before outlining the major theoretical positions developed in the UK. Most British reasoning researchers have contributed to one or more of these positions. We identify a common theme that is emerging in all these approaches, that is, the problem of explaining how prior general …

Bounded Rationality in Taking Risks and Drawing Inferences
This commentary provides a discussion of the concept of `bounded rationality' as it applies to the theses advanced by Lopes (1991) and Evans (1991). Lopes's (1991) assessment of the irrationalist consequences of Tversky and Kahneman's (1974) work on heuristics and biases is premature because bounded rationality implies that people could not employ optimal strategies. Considerations of bounded rationality also provide additional criteria by which …
A rational analysis of the selection task as optimal data selection.
Human reasoning in hypothesis-testing tasks like Wason's (1966, 1968) selection task has been depicted as prone to systematic biases. However, performance on this task has been assessed against a now outmoded falsificationist philosophy of science. Therefore, the experimental data is reassessed in the light of a Bayesian model of optimal data selection in inductive hypothesis testing. The model provides a rational analysis (Anderson, 1990) of the…

Two Realms of Mental Life
What can be learned from positive data? Insights from an ‘ideal learner’. Commentary on ‘A Multiple process solution to the logical problem of language acquisition’ by Brian MacWhinney
MacWhinney's stimulating discussion suggests that there are many lines of argument that may address concerns raised by theorists who are concerned that there is a logical problem of language acquisition. This commentary argues: (1) that if the ‘logical problem’ applied to language, it would apply, with curious consequences to any learning by experience; (2) that the logical problem does not apply – given sufficient positive data from any reasonab…
Information about the logical structure of a category affects generalization
This paper considers whether information about the logical structure of a category affects how people generalize. We carried out three experiments with the following structure: participants were first presented with a set of training items, and were subsequently asked to decide whether new items belonged to the same category as the training items. Each experiment had two conditions that differed only in terms of the category label provided for th…

Bayesian Rationality
For almost 2,500 years, the Western concept of what is to be human has been dominated by the idea that the mind is the seat of reason - humans are, almost by definition, the rational animal. In this text a more radical suggestion for explaining these puzzling aspects of human reasoning is put forward.
A temporal ratio model of memory.
A model of memory retrieval is described. The model embodies 4 main claims: (a) temporal memory--traces of items are represented in memory partly in terms of their temporal distance from the present; (b) scale-similarity--similar mechanisms govern retrieval from memory over many different timescales; (c) local distinctiveness--performance on a range of memory tasks is determined by interference from near psychological neighbors; and (d) interfere…
Seeing is not enough
We show that preferences depend on the attributes that can be directly manipulated when people need to integrate multiple sources of information because direct manipulation causes focusing bias. This effect appears even when all relevant information is simultaneously and explicitly presented at the time the decisions are made. Participants decided how much to save, what investment risk to take and observed the future financial consequences in ter…

Cognition and ConditionalsProbability and Logic in Human Thinking
The conditional, if...then, is probably the most important term in natural language and forms the core of systems of logic and mental representation. It occurs in all human languages and allows people to express their knowledge of the causal or law-like structure of the world and of others' behaviour. The way in which the conditional is modelled also determines the core of most logical systems. Unsurprisingly, it is also the most-researched expre…

Biological Adaptations for Functional Features of Language in the Face of Cultural Evolution
Although there may be no true language universals, it is nonetheless possible to discern several family resemblance patterns across the languages of the world. Recent work on the cultural evolution of language indicates the source of these patterns is unlikely to be an innate universal grammar evolved through biological adaptations for arbitrary linguistic features. Instead, it has been suggested that the patterns of resemblance emerge because la…
