Confirmation Biases

Confirmation Biases

The confirmation bias is the tendency to focus on information that confirms our existing beliefs and ignore information that is inconsistent with our expectations. For example, if you think that your professor is not very nice, you notice all of the instances of rude behavior exhibited by the professor while ignoring the countless pleasant interactions he is involved in on a daily basis. Have you ever fallen prey to the confirmation bias, either as the source or target of such bias?

Ethics and Bioethics

Ethics and Bioethics

Ethics is a philosophical study of moral actions. Ethics attempts to determine what is valuable for individuals and society. It examines the rational justification of moral judgments and analyzes what is morally just, fair, and right. Bioethics is a sub-discipline of applied ethics that analyzes the philosophical, social, and legal issues in life sciences and medicine. Ethical theories serve as a foundation for decision-making and represent the viewpoints from which people seek direction. They...

Ethics in Research

Ethics in Research

Today, scientists agree that good research is ethical in nature and is guided by a basic respect for human dignity and safety. However, this has not always been the case. Modern researchers must demonstrate that the research they perform is ethically sound.

Regulation of Food Intake

Regulation of Food Intake

Short-term regulation of food intake primarily involves neural signals from the gastrointestinal (GI) tract, blood nutrient levels, and GI tract hormones. Communication between the gut and brain via vagal nerve fibers plays a significant role in evaluating the contents of the gut. Clinical studies have shown that protein ingestion produces a more prolonged response in these nerve fibers compared to an equivalent amount of glucose. Additionally, the activation of stretch receptors caused by GI...

Protein Digestion

Protein Digestion

Protein digestion begins in the stomach, where the highly acidic environment can easily disrupt protein structure by exposing the peptide bonds of polypeptide chains. After polypeptide chains are broken into individual amino acids by a series of digestive enzymes, the amino acids are transported to the liver via the bloodstream to produce energy.

Self-Schemas

Self-Schemas

In general, a schema is a mental construct consisting of a cluster or collection of related concepts (Bartlett, 1932). There are many different types of schemata, and they all have one thing in common: schemata are a method of organizing information that allows the brain to work more efficiently. When a schema is activated, the brain makes immediate assumptions about the person or object being observed.

Background:

Previous studies demonstrated that ethical instruction influences student behavior regarding meat consumption.
This research aimed to replicate and extend these findings in a university setting.

Purpose of the Study:

To investigate the impact of ethical instruction on students' attitudes and purchasing behaviors related to meat consumption.
To determine if exposure to factory farming footage enhances the effect of ethical arguments.

Main Methods:

730 university students participated in ethics classes, reading arguments for vegetarianism and engaging in discussions.
Half of the students also viewed a video depicting factory farming conditions.
Student attitudes were assessed before and after instruction, and campus food purchases were tracked via student ID cards.

Main Results:

A significant increase in agreement that eating factory-farmed meat is unethical was observed post-instruction (54% vs. 37%).
39% of students pledged to avoid factory-farmed meat for 24 hours.
Actual meat purchases declined from 30% to 23% among instructed students compared to a control group.

Conclusions:

University-level ethical instruction can lead to measurable reductions in meat consumption.
While attitudes shifted, the addition of factory farming footage did not produce a statistically significant difference in immediate behavioral outcomes or pledges.
The study provides evidence for the effectiveness of ethical education in promoting pro-environmental and ethical dietary choices.
