Reason and Intuition01:37

Reason and Intuition

6.3K
The human brain processes information for decision-making using one of two routes: an intuitive system and a rational system (Epstein, 1994; popularized by Kahneman, 2011 as System 1 and System 2, respectively). The intuitive system is quick, impulsive, and operates with minimal effort, relying on emotions or habits to provide cues for what to do next, while the rational system is logical, analytical, deliberate, and methodical. Research in neuropsychology suggests that the...

Decision Making01:20

Decision Making

74
Decision-making is a fundamental cognitive process that involves evaluating alternatives and selecting among them. This process can range from simple choices, such as deciding what to wear, to complex decisions, like choosing a major in college or a career path. The complexity of the decision often dictates the approach we use, which can be broadly categorized into two types: automatic and controlled decision-making.
Automatic decision-making is fast, intuitive, and relies on gut feelings...

The Availability Heuristic01:08

The Availability Heuristic

5.9K
A heuristic is a general problem-solving framework (Tversky & Kahneman, 1974). You can think of these as mental shortcuts that are used to solve problems. Different types of heuristics are used in different types of situations, and the impulse to use a heuristic occurs when one of five conditions is met (Pratkanis, 1989):

Magnetic Susceptibility and Permeability01:31

Magnetic Susceptibility and Permeability

911
In linear magnetic materials, like paramagnets and diamagnets, magnetization is proportional to the magnetic field intensity. The constant of proportionality, a dimensionless number, is called magnetic susceptibility. The value of the susceptibility depends on the type of material.
When diamagnetic materials are placed under an external magnetic field, the moments opposite to the field are induced. Hence, the susceptibility for diamagnets has a minimal negative value of 10-5–10-6. Since...

Magnetism

6.2K
Magnets are commonly found in everyday objects, such as toys, hangers, elevators, doorbells, and computer devices. Experimentation on these magnets shows that all magnets have two poles: one is labeled north (N) and the other south (S). Magnetic poles repel if they are alike and attract if unlike. Moreover, both poles of a magnet attract unmagnetized pieces of iron.
An individual magnetic pole cannot be isolated. No matter how small, every piece of a magnet contains a north pole and a south...

Introduction to Special Senses01:26

Introduction to Special Senses

5.4K
Sensory receptors play an integral part in comprehending our external and internal environments. They receive diverse stimuli, converting them into the nervous system's electrochemical signals. This conversion occurs as the stimulus alters the sensory neuron's cell membrane potential, instigating the generation of an action potential. This action potential is subsequently transmitted to the central nervous system (CNS), which integrates with other sensory data or higher cognitive...

Summary

Human decision-making is influenced by the geomagnetic field (GMF). Disrupting the GMF significantly hampered subconscious choices in a Go game, revealing a magnetic resonance-dependent mechanism in probabilistic decision-making.

Area of Science:

  • Neuroscience
  • Biophysics
  • Human Sensory Perception

Background:

  • Animals utilize the geomagnetic field (GMF) for navigation and orientation.
  • Human sensitivity to GMF is not well understood.
  • Previous studies indicated deviations between theoretical and empirical probabilities in Go game stone selection.

Purpose of the Study:

  • To investigate the role of GMF in modulating subconscious, non-spatial human decision-making.
  • To elucidate the underlying mechanisms of GMF's influence on decision-making.
  • To use the Go game's binary stone selection as a model system.

Main Methods:

  • Laboratory experiments involving Go game stone selection tasks.
  • Manipulation of the ambient geomagnetic field (GMF) by cancellation.
  • Application of specific magnetic resonance radiofrequency to assess decision-making attenuation.
  • Analysis of stone selection rates in relation to trials and decision-making steps.

Main Results:

  • Cancellation of the ambient GMF significantly hampered experimental probabilities in decision-making.
  • Decision-making attenuation was confirmed within a specific magnetic resonance radiofrequency range.
  • Subconscious stone selection was identified as the primary target modulated in binary decision-making.

Conclusions:

  • The geomagnetic field (GMF) influences subconscious human decision-making.
  • A magnetic field resonance-dependent mechanism underlies the manifestation of theoretical probability into empirical probability.
  • Findings offer insights into GMF's impact on probabilistic decision-making.
