With social networks, it is easier than before to pick up on protest signals as well as for groups to organise themselves, facilitating the demonstration.
The Yellow Vests (“Gilets Jaunes”, in French) are a perfect example of online and offline mobilisation with nearly 4 million members in Facebook groups and over 300,000 people present on the first day of mobilisation in the streets.
As a result of the MeToo movement, there has been a significant rise in sex crime complaints in the US – around +20% between 2017 and 2018 for New York City, for example.
Even if MeToo did not trigger street protests, the stock market crashes and bankruptcy of Harvey Weinstein's company are examples of its effect on the ‘real world’.

With the advent of online platforms, opinions are becoming polarised on many subjects.
Recommendation algorithms, which recommend specific content likely to appeal to users, are one of the main causes of this.
Using analytical and numerical techniques, researchers have simulated the evolution of user preferences according to algorithmic recommendations.
By identifying these strategies, the study could help to develop less-polarising algorithms in the future by increasing user engagement.
This is another step towards creating a more balanced and inclusive online information ecosystem.
