The internet is an echo chamber that will confirm extremists in their views if not stopped  The internet may be a free for all where all ideas and viewpoints can be found but that does not mean that all users view all these views. Instead the internet acts as an echo chamber that encourages people to believe their own views are correct and so get more extreme rather than challenging them. Eli Pariser author of a book called The Filter Bubble argues that the internet forces us to consume a very narrow range of views as search engines have been personalised with the intention of letting users find what they like so two people searching for the same thing on google can get very different results, for example when googling ‘BP’ during the oil spill one person might be directed to information about the spill and its environmental consequences while another might get just investment information. [1] When this kind of filtering is added to people constantly interacting with extremists and on websites praise and incite terrorism it is clear that users of these sites will get caught in a confirmation bias and conformation bias tends to lead to people becoming more polarised. [2] It is therefore the right policy to punish users of extremist websites before they become too radicalised as it is only a very short step from believing an attack is praiseworthy to carrying out similar attacks.
