Listen to your heart (beat): Viscero-sensory feedback leads to better decisions

In a study published in the journal Psychophysiology, the authors claim to provide the first empirical evidence that viscero-sensory feedback from an internal organ is associated with decision-making processes.

Participants with accurate vs. poor perception of their heart activity were compared with regard to their performance in the Iowa Gambling Task.

During this task, participants have to choose between four card decks:

- Decks A and B yield high gains and high losses, and if played continuously, result in net loss
- Decks C and D yield small gains and also small losses, but result in net profit if they are selected continuously

Participants have to learn to avoid the net loss options in favor of the net gain options.

In this study, participants with good cardiac perception chose significantly more of the net gain and fewer of the net loss options.

These findings may provide evidence of the role of visceral feedback in decision-making processes in complex situations.

Twitter lists put users in categories and show what others think of you

Twitter is creating its own ecosystem and hierarchy around the number of followers, list mentions, RTs, etc.

Twitter lists show how others label you, for example, "science-types", "medical-education", "bloggers" or sometimes just "random-people".

In a way, Twitter has put everybody to work on their search product since lists are a way to tag an arbitrary set of real time web feeds. http://bit.ly/3cfoEO


A screenshot of an early version of some of my Twitter lists.

According to @Doctor_V, "You can tell a lot about someone by the lists they keep."
