Years ago, I saw the same split between views on dimensions of morality presented as conservatives vs. liberals rather than believers vs. non-believers.I will be referencing the points of the following article:
Atheists and believers have different moral compasses
Atheists and believers have a moral compass, just not the same one.www.livescience.com
Research indicates that when it comes to morality, Atheists and the devoutly religion all tend to be very moral people. (It seems to be the nominally religious that tend to make excuses why something isn't wrong in their unique case). In both cases, fairness and helping the vulnerable play a dominant role.
However, the researchers found "differences between believers and disbelievers on the other three values: authority (respecting authority figures, such as police, parents and teachers), loyalty (being loyal to one's group, such as a country — not burning a country's flag, for instance) and sanctity (not doing anything perceived as degrading, usually in a sexual sense, such as being promiscuous)."
This seems to be related to the fact that believers are more concerned with group cohesion -- ethics that bind a community together. This is not the first time I have come across a study documenting this.
Another difference that has come up both in this study, and previous studies I have read is that Atheist morality tends to be more outcome based than rule based. Basically, atheists were more likely than believers to base their judgments about what is or isn't moral based on the consequences of their actions.
An example of this is the statistical differences in the two groups in their response to the classic trolley car problem.
For those who don't know what that is, imagine a trolley car going down the track, approaching a division in the track. If left to follow how the track is currently configured, the trolley car will hit and kill 5 people. However, if you pull a switch, it will switch tracks, and kill only one person. Do you pull the switch or do you just allow things to happen without intervention?
"In that situation, the disbelievers are more inclined to say 'flip [the] switch and kill the one person rather than five,' because they are assessing the relative harm," Ståhl told Live Science. "Whereas believers are more icky about that because they feel like they're actively killing someone, and they shouldn't kill. So, they are less comfortable with those calculations."
Now, just for fun, I am including the following video simply for levity. It shows a two year old's solution to the trolley car dilemma.
I wonder where liberal believers fall here.
