Agonism and Antagonism: Quantification01:14

Agonism and Antagonism: Quantification

650
When drugs are administered, they can elicit either an agonist or antagonist effect on the body. Agonism occurs when a drug activates a specific receptor, triggering a biological response. On the other hand, antagonism happens when a drug binds to the same receptors but blocks their activation, thereby preventing a biological response.
To quantify these effects, researchers use a dose-response curve, which provides valuable information about the potency and efficacy of a drug. Potency refers to...

Persuasion Strategies

40.3K
Researchers have tested many persuasion strategies, including the foot-in-the door and the door-in-the-face techniques, in a variety of contexts. Ultimately, the principles are effective in selling products and changing people’s attitude, ideas, and behaviors (Cialdini & Goldstein, 2004).

Machines are complex structures consisting of movable, pin-connected multi-force members that work together to transmit forces. Consider a lifting tong carrying a 100 kg load. It comprises movable sections DAF and CBG linked together with member AB.

The Anchoring-and-Adjustment Heuristic

7.5K
In order to make good decisions, we use our knowledge and our reasoning. Often, this knowledge and reasoning is sound and solid. However, sometimes, we are swayed by biases or by others manipulating a situation. For example, let’s say you and three friends wanted to rent a house and had a combined target budget of $1,600. The realtor shows you only very run-down houses for $1,600 and then shows you a very nice house for $2,000. Might you ask each person to pay more in rent to get the...

The Representativeness Heuristic

16.4K
The representative heuristic describes a biased way of thinking, in which you unintentionally stereotype someone or something. For example, you may assume that your professors spend their free time reading books and engaging in intellectual conversation, because the idea of them spending their time playing volleyball or visiting an amusement park does not fit in with your stereotypes of professors.

Summary

A chatbot effectively improved attitudes toward genetically modified organisms (GMOs) by presenting scientific consensus and rebuttals. While interactive, the chatbot was no more persuasive than a static list of arguments.

Area of Science:

  • Agricultural Science
  • Communication Studies
  • Psychology

Background:

  • Public discourse on genetically modified organisms (GMOs) often lacks nuanced discussion.
  • Interactive communication methods show promise for attitude change but face scalability challenges.

Purpose of the Study:

  • To develop and evaluate a chatbot designed to emulate key traits of persuasive discussion regarding GMOs.
  • To assess the impact of chatbot-delivered arguments on public attitudes towards GMOs.

Main Methods:

  • A chatbot was created to present arguments about GMO safety and rebut common counterarguments.
  • Participants received either a control message, a list of arguments, or interacted with the chatbot.
  • Attitudes towards GMOs and belief updates were measured.

Main Results:

  • Presenting arguments, especially rebuttals to counterarguments, significantly improved attitudes toward GMOs.
  • Participants with initially negative attitudes showed the most significant positive shifts.
  • No significant difference in persuasiveness was found between the interactive chatbot and a static list of arguments.

Conclusions:

  • Chatbots can be a tool for disseminating information and influencing attitudes on complex topics like GMOs.
  • While interactive elements did not enhance persuasiveness over static lists, the structured presentation of arguments was effective.
  • Targeting arguments to address specific counterarguments is crucial for attitude change.
