Summary
This summary is machine-generated.Heterophobia, the repulsion from dissimilar opinions, can prevent social consensus on networks. This effect depends on interaction strength and individual rationality, altering consensus emergence and stability.
Area Of Science
- Social network dynamics
- Sociophysics
- Opinion formation modeling
Background
- Heterophobic interactions, like homophilic ones, significantly shape social network dynamics.
- These interactions influence processes such as opinion formation, social balance, and epidemic spreading.
Purpose Of The Study
- To investigate how heterophobia impacts consensus formation in social networks.
- To analyze the transition from consensus to no consensus under varying heterophobia strengths and individual rationality.
Main Methods
- Utilized belief propagation and Monte Carlo simulations.
- Employed treelike signed graphs to model social interactions.
- Analyzed phase transitions and parameter regions for consensus.
Main Results
- Sufficient heterophobia can impede consensus formation that would otherwise occur via a phase transition.
- The consensus transition shifts from continuous to discontinuous as heterophobia strength and individual rationality decrease.
- Consensus stability shows strong dependence on initial conditions.
Conclusions
- Heterophobia is a critical factor in social consensus dynamics, comparable to homophobia.
- The emergence and stability of consensus are sensitive to the interplay between heterophobia, rationality, and network structure.
- The parameter space for achieving consensus diminishes with an increasing number of topics.

An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...
Random or indeterminate errors originate from various uncontrollable variables, such as variations in environmental conditions, instrument imperfections, or the inherent variability of the phenomena being measured. Usually, these errors cannot be predicted, estimated, or characterized because their direction and magnitude often vary in magnitude and direction even during consecutive measurements. As a result, they are difficult to eliminate. However, the aggregate effect of these errors can be...
A random variable is a single numerical value that indicates the outcome of a procedure. The concept of random variables is fundamental to the probability theory and was introduced by a Russian mathematician, Pafnuty Chebyshev, in the mid-nineteenth century.
Uppercase letters such as X or Y denote a random variable. Lowercase letters like x or y denote the value of a random variable. If X is a random variable, then X is written in words, and x is given as a number.
For example, let X = the...
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.

Speciation describes the formation of one or more new species from one or sometimes multiple original species. The resulting species are discrete from the parent species, and barriers to reproduction will typically exist. There are two primary mechanisms, speciation with and without geographic isolation—allopatric and sympatric speciation, respectively.
Allopatric Speciation
In allopatric speciation, gene flow between two populations of the same species is prevented by a geographic...
Network covalent solids contain a three-dimensional network of covalently bonded atoms as found in the crystal structures of nonmetals like diamond, graphite, silicon, and some covalent compounds, such as silicon dioxide (sand) and silicon carbide (carborundum, the abrasive on sandpaper). Many minerals have networks of covalent bonds.
To break or to melt a covalent network solid, covalent bonds must be broken. Because covalent bonds are relatively strong, covalent network solids are typically...
