Why Angry Blocker?

In this post-truth modern world with endless alternative facts it's very easy to get over emotional, form false judgements, and lose control of our decisions. When we allow emotions to blindly force us to do something we become vulnerable to propaganda. In 2016, both ends of the political spectrum used emotionally charged headlines to influence public opinion on Brexit and Donald Trump. Such news is dangerous when it leads us to make choices we wouldn't have made in our normal emotional state.

Angry Blocker is our first attempt to address this issue. Angry Blocker protects you from negative emotions and helps you to be aware of the type of information you consume online. When you visit selected websites like CNN, FoxNews, BBC, etc. Angry Blocker's proprietary deep neural network estimates the emotional content of the page which you are about to read and notifies you about very sad and angry pages. Then it's up to you to decide whether to read those pages or not. But once notified you are aware and therefore protected from misleading overly emotional reactions and invasive propaganda.

Just like a healthy food diet, we believe that internet users should also follow a healthy information diet. Angry and sad content should be consumed with precaution. Too much sugar and fat can lead to health problems, but at present we've found ourselves in the world with too much anger and hate. Angry Blocker will help to restore a balance, because the world is still a good place.

How It Works

Whenever you visit an angry or sad news page, we will hide the page from you. Instead you will see a nice picture from nature and a message like "This page is too angry for you" with links to "Go back", "See it anyway" or view some better news on our website. Like this:

You will also observe the icon in the top right corner of your browser changing from a question mark question mark icon to the predominant emotion expressed in the page such as love icon for angry. You can click the icon to view the full analysis, showing the percent of each emotion:

Support Angry Blocker

The best way you can support is to tell your friends about Angry Blocker. Because if the idea behind it becomes popular enough, it could impact upon the way articles are written. You can also send us feedback on what you like and what could be improved.

Deep Neural Network

Behind the scenes, the Angry Blocker extension extracts meta tags from the web page you are viewing and sends it to our server. We use our emotional model, a multi-layer recurrent neural network, to analyse the text and estimate the percentages of the following emotions: love, haha, wow, sadness, anger, the same five emotions which Facebook currently uses. It does this by first turning words into vectors and then running a multi-layer recurrent neural network.


So far we have analysed the emotions in 1210 web pages. This is a lot of data and we can do some interesting analysis. For example, you can use this table below to see which media companies produce the most angry articles according to our emotional estimates:
