Confirmation Biases01:31

Confirmation Biases

7.1K
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?

Woodward–Hoffmann Selection Rules and Microscopic Reversibility

3.3K
Electrocyclic reactions, cycloadditions, and sigmatropic rearrangements are concerted pericyclic reactions that proceed via a cyclic transition state. These reactions are stereospecific and regioselective. The stereochemistry of the products depends on the symmetry characteristics of the interacting orbitals and the reaction conditions. Accordingly, pericyclic reactions are classified as either symmetry-allowed or symmetry-forbidden. Woodward and Hoffmann presented the selection criteria for...

Types of Selection

Natural selection influences the frequencies of particular alleles and phenotypes within populations in several different ways. Primarily, natural selection can be directional, stabilizing, or disruptive. Directional selection favors one extreme trait and shifts the population towards that phenotype while selecting against individuals displaying alternate traits. Stabilizing selection favors an intermediate trait with a narrow range of variation. Deviation from the optimal phenotype towards an...

Randomized Experiments

The randomization process involves assigning study participants randomly to experimental or control groups based on their probability of being equally assigned. Randomization is meant to eliminate selection bias and balance known and unknown confounding factors so that the control group is similar to the treatment group as much as possible. A computer program and a random number generator can be used to assign participants to groups in a way that minimizes bias.

Survey Safety

Surveying near highways, rough terrain, or power lines involves significant risks. Working along highways is particularly dangerous and requires the use of warning signs and flagmen. It is safest to avoid working directly on roads and use offsets whenever possible. When highway work is unavoidable, it must follow all safety guidelines. Surveyors should wear bright clothing, such as orange reflective vests, to ensure visibility to motorists, coworkers, and hunters. In construction zones, wearing...

Law of Independent Assortment

While Mendel’s Law of Segregation states that the two alleles for one gene are separated into different gametes, a different question of how different genes are inherited remains. For example, is the gene for tall plants inherited with the gene for green peas? Mendel asked this question by experimenting with a dihybrid cross; a cross in which both parents are homozygous for two distinct traits resulting in an F1 generation that are heterozygous for both traits.

Area of Science:

  • Computer Science
  • Distributed Systems
  • Cryptography

Background:

  • Collusion among malicious participants undermines decentralized protocols.
  • Worker collusion poses significant security risks in critical operations.
  • Existing protocols lack robust mechanisms to prevent worker collusion.

Purpose of the Study:

  • To propose novel protocols for selecting workers in decentralized systems to minimize collusion probability.
  • To enhance the security and trustworthiness of decentralized protocols, particularly voting systems.
  • To provide collusion-resistant worker selection mechanisms.

Main Methods:

  • Developed a decentralized protocol for verifiable random worker selection without trusted entities.
  • Designed an algorithm utilizing social graph analysis and community detection for socially distant worker selection.
  • Applied and evaluated solutions within the context of a decentralized voting protocol.

Main Results:

  • Achieved minimized probability of collusion among selected workers.
  • Demonstrated verifiable and decentralized worker selection.
  • Showcased the effectiveness of social distancing in reducing collusion.

Conclusions:

  • The proposed protocols offer effective collusion-resistance for decentralized systems.
  • Verifiable random selection and social distancing are viable strategies for secure worker selection.
  • These solutions are vital for ensuring democratic and trustworthy decentralized voting.
