Introduction
I am a behavioral data scientist. I combine several techniques from the behavioral sciences, such as psychology, economics, sociology, and business, with computational approaches from computer science, statistics, data-centric engineering, information systems research, and mathematics. This interdisciplinary set of skills allows me to model, understand, and predict human behavior differently.

This paper provides a tutorial for analyzing psychological research data with GAMLSS, an R package that uses the family of generalized additive models for location, scale, and shape. These models extend the capacities of traditional parametric and non-parametric tools that primarily rely on the first moment of the statistical distribution. When psy...
Is it possible to measure how critical soft skills like leadership or teamwork are from the viewpoint of graduate studies offerings? This paper provides a conceptual and methodological framework that introduces the concept of a bipartite network as a practical way to estimate the importance of soft skills as socio-emotional abilities trained in gra...
Is it possible to measure how important soft skills like leadership or teamwork are from the point of view of graduate studies offerings? This paper provides a framework that introduces the concept of network centrality as a practical way to measure the individual importance of soft skills in graduate studies. We examine 230 graduate programs offer...
Several barriers may inhibit the growth of behavior analysis as a more integrated and collaborative field. Two such barriers are siloed environments that reinforce a basic-applied distinction, and a lack of translational research pathways. We describe the perils of silos, and elaborate on potential solutions to increase reciprocal relations among s...
TIME is a highly abstract concept and prevalent in languages worldwide. Cross-cultural and cross-linguistic research suggests that TIME is embodied dissimilarly in different languages. Still the literature has not received sufficient attention in examining the differences. This study aimed to identify and compare how TIME is metaphorically represen...
The Internet is strengthening the e-commerce industry, which is fast growing and helping enterprises of all sizes, from multinational organizations to tiny firms. Customers may buy things online with little or no personal interaction with sellers they purchase online; user reviews play a vital role in online shopping. Consumers’ comprehension and i...
The Myers-Briggs Type Indicator (MBTI) is a popular tool used by psychologists working as managers' coaches in organizational contexts. Despite its popularity, few studies provide empirical evidence on the role of the MBTI as a predictor of managers' leadership-related behaviors. This article is written based on research that answers the question o...
Algorithms, data, and AI (ADA) technologies permeate most societies worldwide because of their proven benefits in different areas of life. Governments are the entities in charge of harnessing the benefits of ADA technologies above and beyond providing government services digitally.

Reducing global warming effects without jeopardizing economic prosperity demands the analysis of the link between these factors. Environmental degradation and economic growth are thought to be related in a non-linear manner, following an inverted-U pattern called the ‘Environmental Kuznets Curve’ (EKC). Despite the many studies seeking empirical su...
Customer’s trust in vendors’ reputation is a key factor that facilitates economic transactions in e-commerce platforms. Although the trust-sales relationship is assumed robust and consistent, its empirical evidence remains neglected for Latin American countries. This work aims to provide a data-driven comprehensive framework for extracting valuable...
This is a Spanish-written talk to be shared on September 21, 2021, in the First International Symposium on Measurement and Evaluation in Social and Health Sciences, organized by Universidad de La Sabana in Bogotá, Colombia.
Based on what we know about thermodynamics of synergy, we explored the relationship between countries socio-cultural order (negentropy), estimated through their constitutions, indicators of Rule of Law and their academic development; with countries indicators of Free Energy (amount of useful work, productivity, socioeconomic health). The analysis o...
Natural language as a data source is quite common in different divisions of psychology. Among the several ways to analyze the information conveyed by natural language, psychologists rarely use bipartite networks despite the strong potential that this network perspective has for enriching psychology's research toolbox. This opinion article aims to p...

Design/methodology/approach – Web scraping, text mining techniques as well as multivariate statistics are combined to uncover the structure of the three tiers of SMD f...
A common practice among clinical psychologists and other health professionals is the use of school-based sexual health promotion programs as a means for preventing sexually transmitted infections. A fundamental criterion for the designing and adaptation of these programs is the age of their target populations because limited education and language...
Forced migration and displacement are two well-known results of internal armed conflicts of nations. A fundamental relationship associated with these humanitarian movements is the one entailing the link between the geographical distance travelled by migrants and their economic well-being. As such a link remains unstudied in previous works, its empi...
In a recent round table organized by the Santa Fe Institute, the complexity of commerce captured the attention of those interested in understanding how complex systems science can be applicable for settings where consumers and providers interact. Despite the usefulness of applied complexity for commerce-related phenomena, few works have attempted t...
Cyberbehavior, as the object of study of cyberpsychology, refers to the set of human behaviors that require an electronic device with Internet access to interact with other persons in both synchronous and asynchronous ways. Although the first studies of cyberbehavior took place with the popularization of the so-called “Social Web", few works focus...
Latin America was fundamental in the intellectual formation of the founders of modern biology (e.g. Alexander von Humboldt, Charles Darwin, Alfred Russel Wallace, Henry Bates and William D. Hamilton), but these pioneers directed their findings primarily to a European audience. Only later did European ethological influence reach Argentina, Brazil, M...
This article proposes the use of computationally efficient inverse regression Bayesian method for analysis of tweet propagation of political messages. Our example focuses on the Colombian case, though our method can be used in any election where social media messaging has a direct impact on political outcomes. We find strong evidence that politicia...
A taken-for-granted factor that facilitates the economic transactions in E-commerce platforms is the customer's trust in vendors' reputation. The empirical evaluation targeting the statistical consistency of the trust-sales relationship, however, remains neglected in the literature. As an exploratory attempt of filling this gap, we provide a data-d...

This data article contains data regarding the collaborative consumption that takes place in an Online Food Delivery Platform that connects restaurants owners, and customers who wish to order meals and receive them at home or office. These data are associated with the article “Evaluation of Collaborative consumption of food delivery services through...
The so-called index of economic complexity, based on nations' exports, was initially proposed as an alternative to traditional macroeconomic metrics just as the scientific productivity of countries which has also been deemed as a better predictor of economic growth. Adequate scrutiny to the relationship between these two factors, however, remains l...
The accumulation of knowledge required to produce economic value is a process that often relates to nations economic growth. Some decades ago many authors, in the absence of other available indicators, used to rely on certain measures of human capital such as years of schooling, enrollment rates, or literacy. In this paper, we show that the predict...
This is a presentation that I expect to share with local colleagues in the next 2019 Colombian Congress of Psychology to be held in the City of Barranquilla.
A brief overview of the scientific research on Artificial Intelligence
Online food delivery services rely on urban transportation to alleviate customers' burden of traveling in highly dense cities. As new business models, these services exploit user-generated contents to promote collaborative consumption among its members. This study aims to evaluate the impact of traffic conditions (through the use of Google Maps API...

Ambos casos se toman como ejemplo para mencionar los retos que plantea esta forma de investigación para la comunidad de psicólogos. La...
El fenómeno del abstencionismo electoral deja en evidencia el poco interés que tiene la población por ejercer su derecho al voto y elegir a sus gobernantes, afectando con ello la legitimidad de las democracias, puesto que cuando se presenta baja participación electoral, se atenta contra el postulado fundamental de la democracia que es ser el gobier...
A peace agreement was recently subjected to a plebiscite as a solution to finish the Colombian armed conflict. With 62.57% of abstention, 18.44% of the Colombian electorate rejected this agreement. This paper aims to propose a methodological approach that shows how to linguistically analyze peace agreements as political products that are acceptable...
The accumulation of knowledge required to produce economic value is a process that often relates to nations economic growth. Such a relationship, however, is misleading when the proxy of such accumulation is the average years of education. In this paper, we show that the predictive power of this proxy started to dwindle in 1990 when nations schooli...
This article has the purpose of establishing which are the variables that allow explaining the behavior of the SJR between 2014 and 2016, for the journals indexed in Scopus. To do this, journals that had a SJR value greater than eight in 2016 were selected, that is, 103 of the 22,231. For the analysis, a model of standard errors corrected for panel...
We argue that making accept/reject decisions on scientific hypotheses, including a recent call for changing the canonical alpha level from p = 0.05 to p = 0.005, is deleterious for the finding of new discoveries and the progress of science. Given that blanket and variable alpha levels both are problematic, it is sensible to dispense with significan...
A brief guidance on how to write a scientific paper from a data scientist point of view.
Surveys and experiments are the standard data sources for consumer behavior research. As a consequence, few studies illustrate the relevance of social networks as a third data source. The aim of this paper is to provide a rationale on why social networks can be both scientifically useful and socially relevant for consumer research. The urban mobili...

We argue that depending on p-values to reject null hypotheses, including a recent call for changing the canonical alpha level for statistical significance from .05 to .005, is deleterious for the finding of new discoveries and the progress of science. Given that blanket and variable criterion levels both are problematic, it is sensible to dispense...
Una charla acerca de los preprints como medios para acelerar la visibilidad de los trabajos científicas, antes de que sean aceptados en revistas arbitradas e indexadas.
A proposed solution to finish the Colombian armed conflict was recently subjected to a plebiscite. Colombians had to support or reject the idea of ceasing the fire and mutual hostilities between the government and guerrilla group “FARC-EP”, along with other socio-economic reforms. Given a 62.57% of abstention, the solution was rejected by only 18.4...
Una charla dirigida a estudiantes de pregrado en psicología para introducir la noción de Sistemas Complejos Sociales.
Despite the popularity of online food ordering services (OFOS) few studies have attempted to understand their value in everyday life. A common motivation for using these services is their convenience for customers since they allow them to avoid traffic jams or traffic congestion in highly dense cities. Is heavy traffic related with patterns of onli...
Snapchat offers a distinctive feature from other social networks in that its users control the visibility of the contents they share with others by defining how long these contents may be available. Snapchat is changing the way men and women perceive online information privacy and content management. This paper aims to illustrate the relevance of s...
This is one of the research products associated to my 2016 institutional research project, titled ”Exploring consumers’ transportation mode choice as patterns of urban mobility”. My Colleague Diana Forero will present this in the next ACR Latin American Conference, 2017. We expect to publish a more extended paper of this topic soon.
Consumer psychology research is said to have a narrow scope but consumer psychologists might extend it by studying urban mobility as a relevant topic of the Transformative Consumer Research. We show an example where decision trees and geo-spatial analyses stand for alternative ways for consumers classification based on their mobility patterns.
The spatio-temporal dimension related to mobility and transportation
can facilitate or inhibit the physical access to health services.
The organization of transportation systems affects travel times
to health services as well as individuals’ desired mobility as it makes
less attractive for them to take additional routes for reaching health

The valence-space metaphor posits that emotion concepts map onto vertical space such that positive concepts are in upper locations and negative in lower locations. Whilst previous studies have demonstrated this pattern for positive and negative emotions e.g. ‘joy’ and ‘sadness’, the spatial location of neutral emotions e.g. ‘surprise’ has not been...
Propagation of political ideologies in social networks has shown a notorious impact on voting behavior. Both the contents of the messages (the ideology) and the politicians' influence on their online audiences (their followers) have been associated with such an impact. Here we evaluate which of these factors exerted a major role in deciding elector...
By employing overly simple rules for mimicking driving behavior in urban traffic, it can be seen a synergistic effect between motorists and motorcyclists in an agent-based environment. When motorcyclists ride in between the available space of stopped or slow-moving vehicles, motorists are forced to reduce their lane-changing maneuvers without affec...
(English abstract / Full text in Spanish) Media use in classrooms favors the development of critical thinking by generating a more meaningful learning, with greater dialogue, socialization and problematization of knowledge between students and teachers. This paper assesses the effect of media use in classrooms on the development of critical thinkin...
This paper illustrates what psychologists can do and learn from the use of intelligent
agent-based simulations, in combination with experimental designs, in order to model the
behavioral interaction of motorists and motorcyclists in urban traffic, when motorcyclists ride in
between the lanes of slow-moving or stopped vehicles. The results of the co...
Automotive traffic is a classical example of a complex system, being the simplest case the homogeneous traffic where all vehicles are of the same kind, and using different means of transportation increases complexity due to different driving rules and interactions between each vehicle type. In particular, when motorcyclists drive in between the lan...

Data mining revealed a cluster of economic, psychological, social and cultural indicators that in combination predicted corruption and wealth of European nations. This prosperity syndrome of self-reliant citizens, efficient division of labor, a sophisticated scientific community, and respect for the law, was clearly distinct from that of poor count...
Background: Emotion words/concepts can be mapped onto space such that positive one are placed in upper locations and negative ones in lower locations. Although this pattern is clear for positive and negative emotions such as ‘joy’ and ‘sadness’, respectively, the location in space of ambivalent emotions such as ‘surprise’ has not been investigated....
CONTEXT The valence-space metaphor posits that emotions map onto space with positive concepts in upper locations and negative ones in lower locations. Whilst previous studies have demonstrated this pattern for positive and Design. For the rating task the IVs were participant (P), language (L), gender (G), handedness (H), age (A), word (W) and word...
