Around the world, things look better in hindsight

Human memory has a pervasive emotional bias – and it’s probably a good thing. That’s according to psychologists Timothy Ritchie and colleagues.

In a new study published in the journal Memory, the researchers say that people from diverse cultures experience the ‘fading affect bias’ (FAB), the tendency for negative emotions to fade away more quickly than positive ones in our memories.

The FAB has been studied previously, but the most previous research looked at the memories of American college students. Therefore, it wasn’t clear whether the FAB was a universal phenomenon, or just a peculiarity of that group.

In the new study, the authors pooled together 10 samples from different groups of people around the world, ranging from Ghanaian students, to older German citizens (who were asked to recollect the fall of the Berlin Wall). In total, 562 people were included.

The participants were asked to recall a number of events in their lives, both positive and negative. For each incident, they rated the emotions that they felt at the time it happened, and then the emotions that they felt in the present when remembering that event.

Ritchie and colleagues found that every cultural group included in the study experienced the FAB. In all of these samples, negative emotions associated with remembered events faded to a greater degree than positive emotions did. Importantly, there was no evidence that this effect changed with people’s age: it seems to be a lifelong phenomenon.

The authors conclude that our ability to look back on events with rose-tinted spectacles might be important for our mental health, as it could help us to adapt and move on from adversity: ‘We believe that this phenomenon is part of a set of cognitive processes that foster emotion regulation and enable psychological resilience.’

However, the authors admit that their study had some limitations. While the participants were diverse geographically and culturally, they all had to speak fluent English, because all of the testing was carried out in that language. In order to confirm that the FAB is truly universal, it will be important to examine it in other languages. Ritchie and colleagues also note that despite this apparent universality of the phenomenon, ‘We do not intend to imply that the FAB occurs for the same reasons around the world.’

This is interesting to me, b/c clearly do not have this. I have difficultly remembering good times and frequently haunted by bad memories.

You're not the only one. I know that I must have had good times in the past because I can recall the events themselves, but emotionally, all I feel are the bad memories -- some from more than 50 years ago.

Yeah this blows my mind... About the only thing i take from my past are my regrets, and those feel COLOSSAL in my mind. All the good memories pale in comparison - and worse - all the good memories lead directly to them.

Every time i try to think of the good times - of my accomplishments and my time well spent with friends and family - regret is always right there staring at me and impossible to ignore. And before long completely drowns out everything else.

To be honest, i'm suspicious of anyone who isn't inflicted with this because in my emotional mind it means that they are probably heartless, even if my intellectual mind tells me that's not necessarily the case.

Isn't this to do with keeping us safe? We remember the tiger eating our relative so as to avoid tigers in the future?
