Leon Festinger’s 1957 A Theory of Cognitive Dissonance is a key text in the history of psychology – one that made its author one of the most influential social psychologists of his time. It is also a prime example of how creative thinking and problem solving skills can come together to produce work that changes the way people look at questions for good.

Strong creative thinkers are able to look at things from a new perspective, often to the point of challenging the very frames in which those around them see things. Festinger was such a creative thinker, leading what came to be known as the “cognitive revolution” in social psychology. When Festinger was carrying out his research, the dominant school of thought – behaviorism – focused on outward behaviors and their effects. Festinger, however, turned his attention elsewhere, looking at “cognition:” the mental processes behind behaviors. In the case of “cognitive dissonance”, for example, he hypothesized that apparently incomprehensible or illogical behaviors might be caused by a cognitive drive away from dissonance, or internal contradiction. This perspective, however, raised a problem: how to examine and test out cognitive processes. Festinger’s book records the results of the psychological experiments he designed to solve that problem. The results helped prove the existence for what is now a fundamental theory in social psychology.

The work of memory researchers Alan Baddeley and Graham Hitch is a prime example of the ways in which good critical thinkers approach questions and the problems they raise.

In the 1960s, researchers into human memory began to understand memory as comprising not one, but two systems. The first was a short-term system handling information for mere seconds. The second was a long-term system capable of managing information indefinitely. They also discovered, however, that short-term memory was not simply a ‘filing cabinet,’ as many had thought, but was actively working on cognitive – or mental – tasks. This is how the phrase “working memory” developed. The hypothesis remained unproven, however, presenting Baddeley and Hitch with the problem of working out how to produce definitive evidence that short term memory was a working system that actively manipulated and processed information.

They responded by designing a series of ten experiments aimed at showing just this – presenting the results in their 1974 article, ‘Working memory.’ The research was a masterpiece of problem-solving that proved revelatory. The authors not only generated new solutions and made sound decisions between alternative possibilities – they also showed that short-term memory is indeed an active system responsible for information processing and managing, while also influencing attention, reasoning, reading comprehension and learning.

While their work has since been refined by others, Baddeley and Hitch’s problem-solving approach helped to create the dominant understanding of working memory that underpins psychological research throughout the world today.

What makes good people capable of committing bad – even evil – acts? Few psychologists are as well-qualified to answer that question as Philip Zimbardo, a psychology professor who was not only the author of the classic Stanford Prison Experiment – which asked two groups of students to assume the roles of prisoners and guards in a makeshift jail, to dramatic effect – but also an active participant in the trial of a US serviceman who took part in the violent abuse of Iraqi prisoners in the wake of the second Gulf War.

Zimbardo’s book The Lucifer Effect is an extended analysis that aims to find solutions to the problem of how good people can commit evil acts. Zimbardo used his problem-solving skills to locate the solution to this question in an understanding of two conditions. Firstly, he writes, situational factors (circumstances and setting) must override dispositional ones, meaning that decent and well-meaning people can behave uncharacteristically when placed in unusual or stressful environments. Secondly, good and evil are not alternatives; they are interchangeable. Most people are capable of being both angels and devils, depending on the circumstances.

In making this observation, Zimbardo also built on the work of Stanley Milgram, whose own psychological experiments had shown the impact that authority figures can have on determining the actions of their subordinates. Zimbardo''s book is a fine example of the importance of asking productive questions that go beyond the theoretical to consider real-world events.

With his 1954 book The Nature of Prejudice, American psychologist Gordon Allport displays the crucial skill of reasoning, producing and organizing an argument that was persuasive enough to have a major impact not only in universities, but also on government policy.

The question that Allport tackled was an old one: why are people so disposed to prejudice against those from other groups? Earlier psychologists had suggested a number of reasons, especially in the case of racial prejudice. Some had suggested that racism was a learned behaviour, conditioned by negative experiences of other races; others that there was an objective rationale to negative racial stereotypes.

Allport, however, reasoned that prejudice is essentially a by-product of the necessary mental shortcuts the human brain uses to process the vast amount of information it takes in. Because our brains want to use as little effort as possible, they regularly fall back on simple stereotypes – which easily generate prejudice. Gathering strong evidence for this hypothesis, he reasoned, clearly and persuasively, that our natural cognitive approach is the most significant factor in accounting for prejudice. Going further still, Allport also reasoned that, once this was better understood, social scientists would be able to influence policy-makers to curb discrimination by law.
