Psychology and Economics come together in a recent line of research, led by Ismael Rodríguez-Lara, Professor at the University of Malaga, who studies how lies affect economic decisions.
It is a study developed together with the Professor at the University of California (Santa Barbara, USA) Gary Charness, considered one of the most influential economists in the world within the experimental area, that has analyzed the way in which morality influences the degree of lying in certain economic situations. The results of this research have been published in the scientific journal Economics Letters.
“In many economic situations such as tax filing or tax fraud, to give a few examples, it is very important to understand when, how and why people lie,” says the UMA researcher.
Based on experiments carried out last year in the United Kingdom, it has been shown that it is the ‘moral costs’, which precisely encompass non-economic aspects, that determine that people lie less. A total of one thousand people have been studied.
“The usual thing is to consider that the degree of lying is affected by economic issues, such as the benefits we obtain or the possible costs that have to be paid, in the form of fines,” explains Rodriguez-Lara, who adds that, however, the results obtained with this research show that morality is also important: “when the information being disclosed is personal, then people lie less than if the information is non-personal,” he says.
In this sense, the Professor of the UMA explains that this is due to factors related to people’s expectations not to disappoint themselves, as well as to differentiate themselves from the rest. “People feel a higher moral cost of lying when the information is personal, because they know it is a lie and they cannot deceive themselves. If that information is non-personal, they deceive themselves into believing that the information they disclose is true,” he says.
According to the Professor, this finding is relevant because “working on the discourse, that is, the way in which the economic issue is raised, could condition the answer, reducing the lie”.
Under the name ‘Personal lies’, this project focused on lying and ethical behavior will be completed with a new line of study that is already being conducted, which also addresses the influence of the effort in lying.
Thus, Ismael Rodríguez, Professor of the Department of Theory and Economic History of the UMA, is going to travel to the United States at the end of February, to Chapman University (California). This research center is home to, among others, the 2002 Nobel Prize in Economics, Vernon Smith.

New exploration in underwater navigation, a team from the Naval University of Engineering in Wuhan, China, has created novel algorithms that rectify inertial errors using sparse acoustic signals. This exploration offers novel method for the issue of underwater navigation , where traditional satellite systems are ineffective due to their signals' inability to penetrate water effectively.
The increasing demand for precise underwater Positioning, Navigation, and Timing (PNT) due to expanding marine exploration and activities highlights the limitations of traditional Global Satellite Navigation Systems (GNSS) ...
Thanks to the rapid progress in tiny tech, we've been mainly using microfluidics to sort tiny particles by size. But now, there's a new way to sort them by shape, which could be a big deal for medical tests and chemistry. This study shows off a new method using sound waves to separate oddly shaped particles from round ones, without needing any labels. This breakthrough could lead to better ways to deliver drugs or diagnose diseases by offering a smarter approach to sort these tiny particles.
In the realm of microfluidics, separating micro-particles based solely on size has been the norm. However, distinguishing these particles ...
Downscaling of electronic devices, such as transistors, has reached a plateau, posing challenges for semiconductor fabrication. However, a research team led by materials scientists from City University of Hong Kong (CityUHK) recently discovered a new strategy for developing highly versatile electronics with outstanding performance, using transistors made of mixed-dimensional nanowires and nanoflakes. This innovation paves the way for simplified chip circuit design, offering versatility and low power dissipation in future electronics.
In recent decades, as ...
Iron is a micronutrient for plants. Biologists from the Institute of Botany at Heinrich Heine University Düsseldorf (HHU) describe in a study, which has now been published in the Journal of Cell Biology, that regulatory proteins for iron uptake behave particularly dynamically in the cell nucleus when the cells are exposed to blue light – an important signal for plant growth. They found that the initially homogeneously distributed proteins relocated together into “biomolecular condensates” in the cell nucleus shortly after this exposure.
Both iron deficiencies and excesses are problematic for plants. They ...
Microbially induced corrosion (MIC) is a prevalent issue in marine environments, leading to structural damages such as cracking in concrete infrastructure. This corrosion poses a persistent challenge, significantly reducing the lifespan of marine structures and resulting in substantial economic losses. In response to the need for an effective solution to combat the marine corrosion on concrete, researchers of the Hong Kong Polytechnic University have developed a biomineralization approach to protect marine concrete from MIC.

Certain genes associated with hypertension affect blood pressure from early in life, and they increase the risk of cardiovascular disease as you get older. However, you can do something about it.
“We are talking about really small differences, so small that they may fall within what is considered normal blood pressure. The problem is that they tend to last your whole life,” says PhD Candidate Karsten Øvretveit at the Norwegian University of Science and Technology's (NTNU) Department of ...
Washington, D.C. — Feb. 23, 2024 —Streams with ample connections to shallow groundwater flowpaths have greater microbial diversity and are more effective at preventing toxic forms of metals—often products of upstream mining—from entering and being transported downstream. These streams are also better at detoxifying those metals already present. The research is published this week in Applied and Environmental Microbiology, a journal of the American Society for Microbiology.
Under favorable conditions, the zone lining a stream channel stores nutrients and oxygen that meet nutritional and respiratory needs of local invertebrates and fish. That ...
Across the globe, more than 39 million people are living with the Human Immunodeficiency Virus (HIV), the virus that causes AIDS, including more than 1.3 million new HIV diagnoses last year. The majority of those afflicted — approximately 76% — have access to antiviral therapy that allows them to live with HIV as a chronic disease.
Sharilyn Almodóvar, Ph.D., from the Department of Immunology and Molecular Microbiology at the Texas Tech University Health Sciences Center (TTUHSC) School of Medicine and the TTUHSC Graduate School of Biomedical Sciences, said that even with the widespread ...

WHO PQ certifies the safety, efficacy, and GMP of a vaccine by evaluating its manufacturing ...
Should we be using polygenic risk score assessment for embryo selection? Providing in-depth analysis, the Social, Ethical and Legal Issues Committee of the American College of Medical Genetics and Genomics (ACMG) has released a new Points to Consider statement to assist healthcare professionals and patients in understanding the safety and utility of preimplantation genetic testing for polygenic disorders (PGT-P) as a clinical service.
“Clinical Utility of Polygenic Risk Scores for Embryo Selection: A Points to Consider Statement of the American College of Medical Genetics and Genomics (ACMG)” was published in the College’s flagship journal, Genetics ...
