The Greater Good Blog posted this great article: Can Emotional Intelligence Be Taught?
Here's the conclusion (good news for all of us).
Delphine and her colleagues found that members of the group that received the training showed a significant improvement in their ability to identify their feelings and the feelings of others, as well as to manage and control their emotions. What’s more, these improvements were apparent not only right after the training but also six months later.
So while this study was a small pilot with a somewhat homogenous group of participants, the findings suggest that it is possible to increase emotional intelligence in the short and long term. “Overall, the results are promising,” write the researchers, “as they suggest that, with a proper methodology relying on the latest scientific knowledge about emotion and emotional processing, some facets of EI can be enhanced, but not all.”
