Most of us can pick without difficulty. We know without a second though which “team” we belong to.

Throughout our lives we all become members of various groups: whether we’re born into them, grow up in them or choose them for ourselves. They give us identities and a feeling of belonging. They provide safety, security and friendship. What happens though when these groups become isolated from each other, and we stop being able to see each other’s points of view?

Although these ideas have been a source of concern for some years, recent world political events such as the Brexit vote or the US election shocked large percentages of the population and popularised the idea of an “Echo Chamber”. This term has come to describe groups which communicate only within themselves, echoing back each others’ beliefs and excluding those around them. Who’s to blame for this? Various culprits have been suggested – Social media, search engine manipulation, the spread of fake news, or our own psychology, to name few frequently vilified candidates. These beg the questions – are echo chambers really such a new thing, or have they always been around? Are they even bad? What positive things can we take from them, and what aspects should we try to break free from?

The next Ar in a Bar, a science communication event organized by scientists from Champalimaud Research, will examine whether our world is becoming divided into Echo Chambers; how we can recognise them in our lives; and what it takes to escape from them.

The event will be held in English but there will be plenty of Portuguese speakers around to facilitate the discussions.

We look forward to breaking free with you!




Ar in a Bar is one of the offshoots of the Ar family (the others being Ar Events and the online Ar Magazine). We aim to create a cosy, friendly atmosphere to have interesting discussions about many different topics in small groups. Our emphasis is on learning together, as part of a community, so we won’t have long talks by individual speakers, but instead will spend most of our time in discussions and explorations of ideas. No prior knowledge of the topic we’re discussing that day, or any scientific training, is necessary.


Why in a bar?

The students at Champalimaud Research have been performing extensive research on themselves and have concluded that beer is beneficial to thinking about science.

What is an event like?

Each evening will have a theme that we hope to explore with the people who come there. We’ll provide 2 or 3 hosts to ignite the discussion, who have been thinking about the topic for a long time. Some will be scientists working in that field, others might be practitioners or otherwise interested in the theme. They will lead various discussions about the topic.

Where are the events held?

Our events are held in the lovely Chimera Brewpub, with the best home-brewed beer in town.

And now the more serious part…

The scientists at Champalimaud Research are seriously concerned about the current state of politics and the world, where evidence is being ignored in favour of rhetoric. This is completely against the principles of scientific research that we live by. We believe more than ever that what is desperately needed is what’s written in Ar’s mission statement: A World Moved by Creative and Critical Thinking. Ar’s various offshoots are our attempt to spread this ideal.
