Editor's Selections: Dunning-Kruger, Flirting, Valentine's Day

Here are my Research Blogging Editor's Selections for this week:

• I believe this is the first time I've featured a cartoon in my weekly editor's selections. Learn all about the Dunning-Kruger effect at Lost in Transcription.
• Krystal D'Costa of Anthropology in Practice asks, Is A Kiss Ever Really Just A Kiss? and provides a nice taxonomy of flirting styles.
• Finally, in honor of Valentine's Day, here's a post on hate. Yes, you read that right. By Melanie Tannenbaum at the ionpsych blog.
