Daniel Goldhagen's study of the Holocaust offers conclusions that run directly counter to those reached by Christopher Browning, whose book Ordinary Men is also the subject of a Macat analysis. As such, the two analyses make possible some interesting critical thinking exercises focused on evaluation of the evidence used by the two historians. For Goldhagen, a chief reason for German actions was not the mundane good comradeship stressed by Browning, but a longstanding hatred of Jews and Judaism specific to Germany that dated back well into the previous century. Debating which...

Milton Friedman was one of the most influential economists of all time – and his ideas had a huge impact on the economic policies of governments across the world.

A key theorist of capitalism and its relationship to democratic freedoms, Friedman remains one of the most cited authorities in both academic economics and government economic policy. His work remains striking not just for its brilliant grasp of economic laws and realities, but also for its consistent application of high-level evaluation and reasoning skills to produce arguments that can convince experts and laypeople...

Few historical problems are more baffling in retrospect than the conundrum of how Hitler was able to rise to power in Germany and then command the German people – many of whom had only marginal interest in or affiliation to Nazism – and the Nazi state. It took Ian Kershaw – author of the standard two-volume biography of Hitler – to provide a truly convincing solution to this problem. Kershaw's model blends theory – notably Max Weber's concept of ‘charismatic leadership’ – with new archival research into the development of the Hitler ‘cult’ from its origins in the 1920s...

American political scientist Robert Putnam wasn’t the first person to recognize that social capital – the relationships between people that allow communities to function well – is the grease that oils the wheels of society. But by publishing Bowling Alone, he moved the debate from one primarily concerned with family and individual relationships one that studied the social capital generated by people’s engagement with the civic life.

Putnam drew heavily on the critical thinking skill of interpretation in shaping his work. He took fresh looks at the meaning of...

South Korean economist Ha-Joon Chang used his 2003 work Kicking Away The Ladder to challenge the central orthodoxies of development economics, using his creative thinking skills to shine new light on an old topic.

Creative thinkers are often distinguished by their willingness to challenge received ideas, and this is a central aspect of Chang’s work on development. Before Chang, the received wisdom was that developing countries needed the same kinds of economic policies and institutions as developed countries in order to enjoy the same prosperity. But, as Chang pointed...
