Sollen wir unserer moralischen Intuition trauen?

Wenn wir das Verhalten von Politikern, Prominenten oder Freunden verurteilen, endet es oftmals damit, dass wir unsere moralische Intuition bemühen. Wir sagen dann:„Gefühlsmäßig ist es einfach falsch.“ Woher aber kommen diese intuitiven Urteile? Handelt es sich dabei um verlässliche moralische Richtlinien?

Außergewöhnliche Forschungsergebnisse haben jüngst neue Fragen über die Rolle intuitiver Reaktionen in der ethischen Argumentation aufgeworfen. Joshua Greene, studierter Philosoph, aber mittlerweile in der Psychologie tätig, kam vor Kurzem von der Universität Princeton nach Harvard und untersuchte, wie Menschen auf gewisse fiktive Dilemmas reagieren. Im ersten Fall befinden Sie sich neben Eisenbahngleisen und bemerken plötzlich, dass ein unbesetzter Eisenbahnwagen auf eine fünfköpfige Menschengruppe zusteuert. Bleibt der Waggon auf seinem Gleis, werden alle fünf Menschen getötet.

Das einzige was Sie tun können, um fünf Todesopfer zu vermeiden ist, eine Weiche umzustellen, so dass der Waggon auf ein Nebengleis umgeleitet wird, wo er nur eine Person töten kann. Auf die Frage, was sie unter diesen Umständen tun würden, geben die meisten Menschen an, sie würden den Eisenbahnwagen auf das Nebengleis steuern und so vier Menschen das Leben retten.

    The Brexit Surrender

    European Union leaders meeting in Brussels have given the go-ahead to talks with Britain on post-Brexit trade relations.

  3. Murdoch's Last Stand?

    Rupert Murdoch’s sale of 21st Century Fox’s entertainment assets to Disney for $66 billion may mark the end of the media mogul’s career, which will long be remembered for its corrosive effect on democratic discourse on both sides of the Atlantic. 

    From enabling the rise of Donald Trump to hacking the telephone of a murdered British schoolgirl, Murdoch’s media empire has staked its success on stoking populist rage.

    The Dangerous Delusion of Price Stability

    Since the hyperinflation of the 1970s, which central banks were right to combat by whatever means necessary, maintaining positive but low inflation has become a monetary-policy obsession. But, because the world economy has changed dramatically since then, central bankers have started to miss the monetary-policy forest for the trees.

  5. Harvard’s Jeffrey Frankel Measures the GOP’s Tax Plan

    Jeffrey Frankel, a professor at Harvard University’s Kennedy School of Government and a former member of President Bill Clinton’s Council of Economic Advisers, outlines the five criteria he uses to judge the efficacy of tax reform efforts. And in his view, the US Republicans’ most recent offering fails miserably.

    The Holy Grail of Genetic Engineering

    CRISPR-Cas – a gene-editing technique that is far more precise and efficient than any that has come before it – is poised to change the world. But ensuring that those changes are positive – helping to fight tumors and mosquito-borne illnesses, for example – will require scientists to apply the utmost caution.
