––– Already heard a lot what humans’ eyes can do? But, below is what you still need to know.
“Moral decisions can be manipulated by eye tracking.”
SCIENCE OF SURPRISES:
–– It used to be quite enigmatic. Now, it speaks aloud. Beware Girls.
Many of the choices we face in daily life have a moral character, from deciding whether to give money to a homeless person asking for change, stopping to tell an address to an old lady to separating out recyclables from the trash.
People often assume that their moral opinions are stable preferences that already exist in their hearts and minds, but we hypothesized that many of your moral decisions may arise ‘on the fly’ as a result of how you look at and interact with your environment.
Using a novel experimental paradigm, the researchers used remote eye-trackers to monitor participants’ gaze while they thought about complex moral questions such as, ‘Is murder sometimes justifiable?’
––– This is how eyes speak, clear and loud, that even nearby store can understand you are over budget today.
The participants were presented with two alternatives to each question, and were asked to consider which those they considered to be morally right. Although they were completely unaware of it, participants’ eye movements were determining when they were told to make their decision. For each trial, a target alternative was randomly selected, and once the eye tracker registered that the participants had looked at the target for a certain amount of time, they were asked to make their decision immediately.
The results showed that the participants’ moral decisions were systematically biased towards the target. Overall, they choose the randomly selected alternative as their own moral opinion in 58% of trials, rather than 50% without the manipulation.
“What we find in this study is that the precise timing of our decisions can be a powerful influence on the choices that we end up making. The process of arriving at a moral decision is not only reflected in people’s eye gaze but can also be determined by it,” one of the researches explains.
The participants were influenced without being presented different arguments or information; instead, the paradigm exploits the fact that where people look reveals their moment -by- moment thought processes. This suggests, says researcher, that the process of arriving at a moral decision is intertwined with process of looking at the world, and more generally, that peoples’ decision processes are reflected in their eye gaze.
“In other words, the same interplay between the brain the hand and the eye that plays out when we reach for a cup of coffee, is also involved in reasoning if something is morally right or wrong,” quotes a researcher enthusiastically.
The study is the first to demonstrate causal links between and gaze and moral choices, but builds on previous work on how gaze is reflected in simple choices, like those between foodstuffs.
Scientists already knew that when we look back and forth between two items on a menu, for example, our gaze patterns reveal what we might choose. Our main contribution is to show that by controlling exactly when someone makes a decision, we can influence what they decide.
Today, all sorts of sensors are being built into mobile phones, and they are even able to track eye movements. Simply by monitoring small changes in our behaviour, these devices have the potential to aid our decisions in ways that have not been possible before.
