  There has been an increasing interest in inferring some personality traits
from users and players in social networks and games, respectively. This goes
beyond classical sentiment analysis, and also much further than customer
profiling. The purpose here is to have a characterisation of users in terms of
personality traits, such as openness, conscientiousness, extraversion,
agreeableness, and neuroticism. While this is an incipient area of research, we
ask the question of whether cognitive abilities, and intelligence in
particular, are also measurable from user profiles. However, we pose the
question as broadly as possible in terms of subjects, in the context of
universal psychometrics, including humans, machines and hybrids. Namely, in
this paper we analyse the following question: is it possible to measure the
intelligence of humans and (non-human) bots in a social network or a game just
from their user profiles, i.e., by observation, without the use of interactive
tests, such as IQ tests, the Turing test or other more principled machine
intelligence tests?
