# The hipster effect: When anti-conformists all look the same

@article{Touboul2019TheHE, title={The hipster effect: When anti-conformists all look the same}, author={Jonathan Touboul}, journal={Discrete \& Continuous Dynamical Systems - B}, year={2019} }

In such different domains as neurosciences, spin glasses, social science, economics and finance, large ensemble of interacting individuals following (mainstream) or opposing (hipsters) to the majority are ubiquitous. [...] Key Result Beyond the choice of the best suit to wear this winter, this study may have important implications in understanding synchronization of nerve cells, investment strategies in finance, or emergent dynamics in social science, domains in which delays of communication and the geometry of… Expand

Anti-Conformism in the threshold Model of Collective Behavior

- Computer ScienceSSRN Electronic Journal
- 2019

A first study of the threshold model, where both conformist and anti-conformist agents coexist, is provided, and the existence of cascade effects is interested, as this may constitute a undesirable phenomenon in collective behavior.

Anti-conformism in the Threshold Model of Collective Behavior

- Mathematics, Computer ScienceDyn. Games Appl.
- 2020

A detailed study of the threshold model, where both conformist and anti-conformist agents coexist, and shows that for most societies, the opinion converges to a chaotic situation.

Climb on the Bandwagon: Consensus and Periodicity in a Lifetime Utility Model with Strategic Interactions

- Mathematics, Computer ScienceDyn. Games Appl.
- 2019

It is discovered that bandwagoning can be persistent at the macrolevel, and there is evidence, also on the basis of numerical simulations, of endogenously generated periodicity.

Hipsters on networks: How a minority group of individuals can lead to an antiestablishment majority

- Physics, Computer SciencePhysical review. E
- 2019

This paper considers a model in which spreading follows a deterministic rule for updating node states (which indicate which product has been adopted) in which an adjustable probability pHip of the nodes in a network are hipsters, who choose to adopt the product that they believe is the less popular of the two.

Social physics

This work reviews the current state of the art in social physics by reviewing a set of topics that are at the heart of modern human societies, and concludes that the future for social physics is bright.

A general model of binary opinions updating

- Computer ScienceMath. Soc. Sci.
- 2021

This work generalises Grabisch and Rusinowska (2013) to non-conformist societies, and introduces a notion of groups based on the signs of influence, which can be hosted by any kind of opinion updating model.

RHYTHMIC BEHAVIOR IN LARGE SCALE SYSTEMS : A MODEL RELATED TO MEAN-FIELD GAMES

- 2016

Systems comprised by many interacting components may exhibit, in the thermodynamic limit, time-periodic behavior in some macroscopic observable. When the microscopic dynamics are described by…

Incentives for Conformity and Anticonformity

- 2020

We study how social evaluation affects conformity and anticonformity in theory and in an experiment. In theory, we show that negative social evaluation, i.e., potential punishment, creates incentives…

Rhythmic behavior in a two-population mean-field Ising model.

- Mathematics, PhysicsPhysical review. E
- 2016

It is shown that the system may undergo a transition from a disordered phase, where the magnetization of each population fluctuates closely around zero, to a phase in which they both display a macroscopic regular rhythm.

Delay-Induced Periodic Behaviour in Competitive Populations

- MathematicsJournal of Statistical Physics
- 2021

We study a model of binary decisions in a fully connected network of interacting agents. Individual decisions are determined by social influence, coming from direct interactions with neighbours, and…

Dynamics of spin systems with randomly asymmetric bonds: Langevin dynamics and a spherical model.

- Physics, MedicinePhysical review. A, General physics
- 1987

The Langevin dynamics of fully connected spin systems whose interaction matrix contains a random antisymmetrie part are studied, in which the spins are linear variables except for a global constraint on the total level of their fluctuations.

Limits and Dynamics of Stochastic Neuronal Networks with Random Heterogeneous Delays

- Mathematics, Physics
- 2012

It is shown in several examples that not only the averaged delay, but also the dispersion, govern the dynamics of such networks, and that the network equations converge towards a delayed McKean-Vlasov equation with distributed delays.

Noise-Induced Behaviors in Neural Mean Field Dynamics

The solutions are Gaussian, and their moments satisfy a closed system of nonlinear ordinary differential equations (ODEs), which are much easier to study than the original stochastic network equations, and the statistics of the empirical process uniformly converge towards the solutions of these ODEs.

Limits and Dynamics of Randomly Connected Neuronal Networks

This work analyzes the mesoscopic and macroscopic limits of networks with random correlated connectivity weights and delays, and addresses both averaged and quenched limits, and shows propagation of chaos and convergence to a complex integral McKean-Vlasov equations with distributed delays.

The relaxation time of the autocorrelation function is calculated and it is shown that the system remains paramagnetic even at zero temperature (T=0), and the fully asymmetric system is ergodic, with decaying autcorrelations, in agreement with the theoretical predictions.
