Personality and Places

Our paper examining the link between individual personality and the places people visit has just been published in Computers in Human Behavior. It’s open access, so you can go read it for free, now

In an experiment we ran previously, we asked users of Foursquare to take a personality test and give us access to their checkin history. The personality test gives us a measure of how each person scores for five different factors: Openness, Conscientiousness, Extraversion, Agreeableness and Neuroticism. The checkin history lists all the places they’ve ever checked in to using Foursquare. Because a couple of hundred people took part in the experiment, we ended up with a large number of individual personalities that we could link to over a hundred thousand venues. In total, this represents a pretty staggering half a million Foursquare checkins that we have personality data associated with.

Our first step with this data has been to see if there are any links between personality factors and the places people choose to visit, and we found some interesting connections.

One of our main finding shows that the use of Foursquare for recording checkins seems to correlate well with Conscientiousness. The more conscientious a user is, the more likely they are to have checked in at more places and to have visited more venues. This could be because people with a high Conscientiousness score tend to be quite organised and disciplined, and so are more likely to remember to check in at every place they visit.

The opposite is true for Neuroticism: the more neurotic an individual is, the fewer places they have visited. Neuroticism is associated with negative feelings, and a tendency to be less social, which could then translate into people going to fewer places, and so checking in less. This is expressed again when we look at only those venues classed as ‘social’ (i.e. – somewhere you would go to hang out with friends). The more neurotic someone is, the fewer ‘social’ venues they have been to.

Surprisingly, we have found no link between Extraversion and the number of social venues visited. It may be expected that extraverts (who are very social in their nature) may go to more social venues. However, the data does not support this. In fact, we find no link between Extraversion and any aspect of Foursquare checkins that we have examined so far.

The personality factor of Openness is related to feelings of creativity and artistic expression, and a willingness to experience new things. It is interesting to find that there is a link between Openness and the average distance travelled between checkins – the more Open an individual is, the further they tend to have travelled. This could be an expression of an Open individual’s desire to experience new things exposing itself through wider travel, and a larger geographic spread of checkins. However, we do not find any link between Openness and the number of different categories visited by a user. We do not see a desire for new experiences express itself in the range and diversity of places visited.

Ultimately, this data could be incredibly useful in improving venue recommendation systems. Current systems use many different information ‘cues’ to recommend to a user a place they might like to visit. These cues include things such as where they have been in the past, where their friends have been, or where is popular nearby. Perhaps by including aspects of an individual’s personality (so including aspects of why they might visit somewhere) we can increase the usefulness of these recommendations.

There is still a lot of analysis to be done on this data, and both myself and Nyala Noe are busy churning through it to discover other links between personality and the places people visit. As we find more interesting connections, I’ll post more here.

 

Extended Mind Crowdsourcing

Update 13/01/15: the paper containing the research described below is currently available from the HICSS website

This post is one I’m cross-posting both here and on the MobiSoc blog. Here, because it’s my personal translation of one of our latest research papers, and there because it’s a very good paper mostly written and driven by Roger Whitaker, so deserves an ‘official’ blog post!

A lot of use is made of Crowdsourcing in both business and academia. Business likes it because it allows simple tasks to be outsourced for a small cost. Researchers like it because it allows the gathering of large amounts of data from participants, again for minimal cost. (For an example of this, see our TweetCues work (paper here), where we paid Twitter users to take a simple survey and massively increased our sample size for a few dollars). As technology is developing, we can apply crowdsourcing to new problems; particularly those concerned with collective human behaviour and culture.

Crowdsourcing

The traditional definition of crowdsourcing involves several things:

  1. a clearly defined crowd
  2. a task with a clear goal
  3. clear recompense received by the crowd
  4. an identified owner of the task
  5. an online process

The combination of all these things allows us to complete a large set of simple tasks in a short time and often for a reduced cost. It also provides access to global labour markets for users who may not previously have been able to access these resources.

Participatory Computing

Participatory computing is a related concept to crowdsourcing, based around the idea that the resources and data of computing devices can be shared and used to complete tasks. As with crowdsourcing, these tasks are often large, complex and data-driven, but capable of being broken down into smaller chunks that can be distributed to separate computing devices in order to complete the larger task. BOINC is a clear example of this class of participatory computing.

Extended Mind Crowdsourcing

The extended mind hypothesis describes the way that humans extend their thinking beyond the internal mind, to use external objects. For instance, a person using a notebook to record a memory uses the ‘extended mind’ to record the memory; the internal mind simply recalls that the memory is located in the notebook, an object that is external to the individual.

Extended mind crowdsourcing takes crowdsourcing and participatory computing a step further by including the extended mind hypothesis, to allow us to describe systems that use the extended mind of participants, as represented by their devices and objects, in order to add implicit as well as explicit human computation for collective discovery.

What this means is that we can crowdsource the collection of data and completion of tasks using both individual users, their devices, and the extended mind that the two items together represent. Thus by accessing the information stored within a smartphone or similar personal device, and the wider internet services that the device can connect to, we can access the extended mind of a participant and thus learn more about his or her behaviour and individual characteristics. In essence, extended mind crowdsourcing captures the way in which humans undertake and respond to daily activity. In this sense it supports observation of human life and our interpretation of and response to the environment. By including social networks and social media communication within the extended mind, it is clear that while an individual extended mind may represent a single individual human, it is also possible to represent a group, such as a network or a collective using extended mind crowdsourcing.

By combining the ideas of social computing, crowdsourcing, and the extended mind, we are able to access and aggregate the data that is created through our use of technology. This allows us to extend ideas of human cognition into the physical world, in a less formal and structured way than when using other forms of human computational systems. The reduced focus on task driven systems allows EMC to be directed at the solving of loosely defined problems, and those problems where we have no initial expectations of solutions or findings.

This is a new way of thinking about the systems we create in order to solve problems using computational systems focused on humans, but it has the potential to be a powerful tool in our research toolbox. We are presenting this new Extended Mind Crowdsourcing idea this week at HICSS.
