Babies have no moral compass - NZ study
It turns out babies don't have a moral compass after all, New Zealand researchers have found.
An Otago University study has quashed the findings of a landmark 2007 Yale study which found that infants could tell the good guys from the bad guys.
The prestigious university's study became an international sensation as it was the first to suggest that babies could assess individuals on their behaviour towards others. The findings have become widely accepted since the study was published, and more than one hundred other research papers have referred to it, which is a signal of its success, Otago University postdoctoral fellow Dr Damian Scarf said.
But Scarf and his Otago University colleagues were suspicious of the Yale findings, and since discussing their own research with international colleagues, they've found out they weren't the only ones.
The team decided to conduct their own experiment to see whether babies did indeed have a moral compass, or whether they just had a preference for "attention grabbing events".
They simulated Yale's original experiment, which used wooden figures attempting to climb a hill.
In one scenario, babies would watch as another figure - the helper - would come and push the climber up the hill, and once it reached the top it would bounce, as if it was doing a little dance. Another scenario showed the climber reaching half-way and then being pushed down the hill by another figure, the hinderer. It did not bounce after reaching the bottom of the hill.
The majority of babies preferred the scenario which included the helper, which the Yale study said indicated that babies had the innate capability of determining one's moral character.
The Otago University experiment used identical materials to the Yale study, the only difference was that the character's eyes moved whereas they were fixed in the American study.
When replicating the Yale study, 12 out of 16 infants chose the helper over the hinderer. But then the Otago team changed things around, and made the climber who was pushed to the bottom of the hill do a dance, while the climber who was pushed to the top remained still. In this case, 12 out of 16 infants chose the hinderer over the helper.
When both climbers - one reaching the top with assistance from the helper and one being pushed to the bottom by the hinderer - did a dance, it was an even split, with eight infants choosing the helper scenario and eight choosing the hinderer scenario.
"We thought the infants were just associating the helper with the bounce. We thought if we switched just the bounce and kept everything else the same that it would be interesting to see what happens," Scarf said.
The study showed that morality was not innate, he said.
"It is something that develops with experience."
The study was conducted in 2010 but only published in the online journal PLOS ONE last week.
The researchers had attempted to have the study published in Nature, where the original Yale study first appeared. But Yale researchers fought against it being published in Nature, claiming that it wasn't done efficiently enough because of the difference in the character's eyes, Scarf said.
"They're obviously not very happy."
Nature rejected the study, but others have welcomed it. At an international psychology conference last year Scarf was enthusiastically applauded following his speech, which detailed the study's findings. Several prominent developmental psychologists around the world have also sent him emails praising him for his work.
Scarf hopes that the Otago study will encourage further research into whether infants possess a moral compass, and that the debate continues.
