with a massive win on saturday the other 2 promoted science part of bone and cologne made unhappy put us in this league of returns and the surprise of the weekend's champions by dropping points against head to the curtain raiser on friday you're watching news from up next world stories the weekend reports we'll have more news headlines at the top of the hour with i'm rebecca racist thanks for joining me. today don't miss our highlights. program. w dot com highlights. sleep.

to be. discovered. subscribe. documentary. a book is a lizard man we're being poisoned by cam trails that aircraft leave behind and german chancellor angela merkel is hitlist secret daughter social media is full of conspiracy theories like these and many videos supporting them figure prominently on the net why is that and how does social media help to promote conspiracy theory is our topic based on.

does this happen to you the auto play feature on you tube plays a strange video which seems to fit with what you just see. you don't know whether to be irritated all fascinated but you keep on watching so when you find yourself sucked into a parallel universe of alternative beliefs videos on conspiracy theories seem to do quite well on you tube and for some of us at least its algorithm keeps recommending more and more of them they can be disturbing but it's hard to look away so let's take a closer look at the world of conspiracy theorists. reptilians the illuminati aliens conspiracy theories often postulate that the world is controlled by a small group of strange elites that harm ordinary folks but luckily there's youtube where evil doers bent on world domination are unmasked. here are our top 3

conspiracy theories. number one the moon landing is a myth. july 20th will mark the 50th anniversary of apollo 11 landing on the moon. but many conspiracy theorists are firmly convinced that no astronaut ever laid a foot on the lunar surface. they claim that the u.s. government staged the 1st moon walk in a film studio as a show of american power and to prove nasa's capabilities. the alleged proof is there are no stars in the lunar sky because the pics were shot in front of a black screen. and the flag looks to be flapping though there's no breeze on the. dubious evidence for this supposed hoax is everywhere on the internet. number 2 the earth is a disk or at least that's what flat earth believes in the us they often hold

conferences to compare notes flat earth or think our world is a disk some even say there's an ice wall around its edge which they claim is antarctica their proof access to the antarctic is restricted to certain people. how's that for logic. number 3. leave trails of condensation contrails in their wake but conspiracy theorists believe that these white line shaped really chemicals which have been sprayed into the atmosphere. or even worse. and who's behind it they say. 3 examples of conspiracy theories that remain popular even though they've been repeated scientifically. when it comes to communication the internet office both unities and risks it allows us to exchange information quickly and easily everyone has a voice but in many bad forms no one checks the validity of the content that's called

fact checking so the web is also full of misinformation online even the craziest concepts find an audience but why videos that spread the crudest conspiracy theories so popular on you tube is it because the platforms users are especially interested in them and why do they keep on turning up in my feet i certainly haven't been searching for them french i t specialist lot used to help programme you tube algorithm today he is one of the platforms most vocal critics he reveals via provocative content always ranks high on social media younger ism is never going to try to find the best. videos that demonstrates ideas he's wrong in take minutes because that would be a total failure from the point of view of the old recent days no fair algorithm i mean it's it's a myth and then goes and comes to share and then person is going to have one goal

only it's going to go for the story right now as the goal is to make a you tube. as. the guest possible. whether for you tube or other social media the and the reason is program to fascinate not teams will be a means to keep uses on the signs for as long as possible. to more polarizing the content the morning 1900 that uses will stay glued to their screens for instance that theory is just extremely good basically or isn't whereas like some very solid scientific explanation that's less of a click bait that and we'll be considered bad because it makes basically less money for. for you if you ball facebook. and other social media earn their money through advertising and the more uses of us sites content the more companies can challenge

for space along with a few counted and interaction rate watch time is a decisive criterion which algorithms used to select content fields ends. with bad phone arising content and often strange ideas conspiracy theory feed use generate lots of time very crazy fake informations are really good because you're like is that true you want to know so you click on your trade to look for bit to see if it's true on ups and even if you click on new look fall like face minutes on the site over the best resource ultimately. then he agrees and is still going to consider that as a success. that's a fanfic you tube's algorithm isn't program to deliver valuable information its goal is to keep me on the side for as long as possible because you tube isn't just a video platform is also an advertiser stream the more clips i look at the more as they can show me so the algorithms goal is to maximize watch time as programs so

that the next video will be even cooler and more exciting than the last so of course i would want to stay tuned it's addictive a bit like eating potato chips though at some point the bag of chips is empty whereas with you there's always another video up next. people watch more than $4000000.00 videos every minute and every minute more than 400 hours of content is uploaded onto the platform no wonder fans of conspiracy theories can find plenty of proof to support their ideas but you don't have to go hunting for these videos they're also shown to users who seem like they might be open to. social media can really read the minds of their users thanks to the masses of personal data available to them. so they also know which people are most susceptible to watching content involving conspiracy theories. and he's going to

find the most vulnerable people on try to brainwash them with a conspiracy between be like they we see like on the roads of times of conspiracy after some time that you start to believe like it's a test to be true because i got like $200.00 recommendations on the flattest maybe it's true. psychologists say people who believe conspiracy theories are looking for simple answers about how the world works they often believe it's controlled by an all powerful force and on the net no one's making sure they're not being fed deliberate gives information we've seen that it's conspiracy theories on the rise in and in many countries on tape vixen conspiracies like people taking less vaccines now people are dying from lack of vaccination in europe. so we see that this says very serious issues. and it's a serious issue with real life consequences for example measles is on the rise in

many places because many people are refusing to vaccinate and measles is a very contagious disease and can cause disability or even death and have access believe that scenes holds a health risk they find lots of reinforcement for their beliefs on you tube thanks to its algorithm. a recent study found that anti vax theories disseminated by fewer than 20 you tube channels reached more that 170000000 people in the past decade you tube's algorithm promotes the dissemination of controversial videos extreme content delivers watch time and that brings revenue google's parent company alphabet doesn't publicize how much money you've makes but analysts estimate it raked in some 13000000000 euros in 2018 that's a lot of cash but wasn't google's old model don't be evil so if the company wanted to stop the spread of conspiracy theories could it can you program algorithms to push informative content instead. no believes it can be done you could totally

value as a thought you made towards facts so as as soon as there would be a public awareness thinking that we can't continue we said here is a recommending a. false statement like that because it's just going to be a disaster for society in 04 and. as soon as the sevens as soon as people are willing to use i'll turn it use on i was reading to pay for eternity use then you can use it in technique you can easily build your systems. the platform operators are more interested in providing clean paint and providing factual information scientific facts often aren't as entertaining but conspiracy theories attract attention and get plenty of views in spite of the often terrible events they show mine for 911 terrorist attacks. to this day some people still believe that the us government was behind the attacks on the world trade center they claim the twin

towers went brought down by hijacked planes but were blown up in stand. refuses to delete such controversial videos even though they contain pay to lay false information instead. the platform operators plan to display takes from wikipedia articles alongside him. doesn't believe this approach will do much to help and once i get a very engaging very exciting video content that's going to convince you of something on the other side you have like this boring wiki page article and you don't know wrote it. so you start thinking is going to be less efficient never mind the fact that we could pedia isn't always the most reliable source of information the social media algorithms field or what we see and what we don't so we have to be aware that algorithms neutral there are a means to an end and for you tube that end is to make money that's what most

companies want but they also have a duty to their uses and should play by the rules we also need to think about how to combat misinformation and hate content effectively and personally i'd like companies to be more transparent about how their algorithms work as users we must understand that not everything on the net can be taken as the gospel truth. should we put pressure on owners to take responsibility for the content on their platforms do we need to regulate the programming of algorithms join the discussion on d.w. dot com on facebook and on our you tube channel there you'll also find a detail explain about how you tube's algorithm works and still next.

to me model you need to see a new addition. to this in. the future generation would. be just be nice if i. could check you i like. to call these. welcome aboard. make yourself comfortable. please try origins like food. and our fitness center. enjoy the spectacular view. point your fellow who wishes you
