Lügen - Erkenne ich wenn ich angelogen werde?

- Julia, how are you? - Oh, yes, right? - If you had answered correctly. - I wouldn't have liked that. - Then I would have said that this was already your first lie and our conversation. Because that's actually true. On the other hand, we don't want to have a complex answer to the question "how are you?" But I mean, we lie the whole day. That's the way it is. But the question is with a really big lie, with a proposal. If I want to sell you a car and you say "Oh, no, he's definitely unfaithful, right?" Can I then recognize if my opposite lies? Is there any kind of sugar on your eye or a wobbling in your knees? Maybe you know that from TV from criminal movies. Is that really what we're talking about in this episode? Besides, we're talking about public problems. For example, in the train or in a hotel or in a burger shop. Is that still as insecure as before when you lock yourself in there? Because there is also a lie. There are possibly robbers who build up such railways that look like that from a hotel. But that's not it at all. And then data is taken away. How dangerous are these public railways hotspots and do we even need in times where there are these data flat rates? That's what we're talking about today. I'm Sebastian Sontag. Bye! Well, of course, we all lie. Every day, with small things, often out of friendliness, often we don't even notice it ourselves. But there are also these larger lies in the work context, for example. Or, as I just said, if you want to buy a car or sell it, you may lie to yourself a little bit. Can I somehow recognize if my opposite lies? In series or films, it's always totally easy. Then the suspect pulls him out of his ear, very briefly with his mouth open, and "Zack!" Do you know the investigator or the investigator? Wait a minute! He's lying. So the lie has written us in the face. Really. Julia Trams from the Quarks team. Can I as a non-serial investigator, as normal in everyday life, then also recognize if someone is lying to me or if it's just Hollywood? Well, unfortunately, I have to disappoint you. It's actually all just Hollywood. So these really clear lie signs. And are they still so small and minimal, perverted, like in the film or in the series? Unfortunately, they don't exist. And unfortunately, no super experts who can just see or hear this, they just lie. But in the film, then all, I don't know, sweat, yes? You can see the pearls on the forehead, yes? They lie, yes? Or they look up to the sky, knead the hands, stumble. I mean, there I can see it quite clearly. Well, but that's not a proof that he or she is just lying, right? So it can also be that he or she, in the face of the intense questions, is just totally stressed. So a physical stress reaction is unfortunately not a proof for a lie. We can only go out of the lie if the story is somehow not right, but not now, because someone swears. - Too bad. - Very. It doesn't mean that we can see lies in a personal context. So for people who we really know very well, why is that not possible? Yes, of course, there are many ideas and studies to lie, but it already starts with the experiments that are made in the research, that they often have nothing to do with the reality of life. So for example, dice games will be carried out where the testers should then lie. Okay, yes, that probably has little to do with the real life, or you are just passionate dice players. Exactly. And even more important, this deception, the lie, that follows instructions, right? That's right, that's also difficult, of course. Yes, and then these studies actually always take place in the laboratory, so no realistic situation. And then that's often question marks, right, which the testers and testers should fill out. So this interaction between the liar and the potential liar is missing. Yes, and then there comes another factor, because we tend people to make assumptions about what we assume that our opponent expects from them. Yes, so you call it the answer tendency or response bias in English. But does it mean that the participants actually also lie there, right? Yes, not consciously, but of course they say what they think is expected. So you see, lying is a really difficult field of research, and even if an indicator comes out of a study that points out lies, then no one can say with certainty whether this laboratory is even allowed to be transmitted from real lies. Because lying is also a totally complex process. Why is that so? Well, you have to keep the truth secret, you have to think out a key alternative story. Then you have to put yourself in the opposite direction at the same time to assess what he might now believe, or what might come as the next question or reaction. Yes, and of course also very important, you have to have mysterious feelings in your grip. So something like fear of discovery or the joy of putting the other person in right now. Maybe you shouldn't get that in the opposite direction. So in any case, you just have to put yourself in the right direction, something like sadness or sadness. Yes, and with this whole number also look authentic. Okay, if you're so quiet, then it sounds like a complex situation, and maybe you know it yourself. If you want to keep something for yourself, because you haven't experienced it all yet, or whatever, then it's really hard for me. And I always have the feeling, well, it already looks different to me, that I somehow don't really know what the truth is. And even if there are no signs for lying, I actually find it a bit wonderful. Well, of course there are such and such lies. You have to say which ones immediately break under the pressure of the lie, for example in the hearing, which simply can't do that well. But now from a swearing or a micro expression in the face of a lie, that just doesn't work. Because there is already the theory wrong. So if someone has fear in a hearing, for example, it doesn't mean that he lies, and maybe he just has fear. That's why lie detectors are so unreliable. Because people are already stressed in the situation, no matter if they lie or not, if you're lying on something like that. Exactly. So these so-called polygraphs measure how fast the heart beats, or if the person starts sweating. However, some people react to a question alone with stress, no matter if they lie or not. Others remain totally cool when they lie. And if someone is very self-confident, then we also fall pretty safe into his lies, because someone who speaks eloquently, we also trust him more and more than someone who is very insecure and maybe talks a little quiet and quiet. We are again at the salesman or the salesman, but the influencer, because we often believe him, if you then get convinced enough. In the end, there is no real chance of falsehood or lies. So that's really looking at you. It looks pretty bad. So the research shows that in most cases, there is a lie to be found in the area of the accident. Even parents don't recognize the lies of their own children better than someone strange. This has been shown by a study from Canada. So even a very close relationship does not protect us from being lied to without noticing. Maybe it only helps to activate the inner factor checker a little, to pay a little attention to it. Yes, what does the person now have against me for interests? Maybe it makes her or him transparent how she gets to her statement. There are negotiable sources. Of course, that is particularly important when it comes to statements by politicians, but also by influencers, influencers and media makers. And how that works? So we talked about activating this inner factor checker a while ago. The appropriate episodes, we'll put them in the show notes and use all the important links to the sources that Julia has used here. Exactly, of course, negotiable. But we will not end up keeping the lies to ourselves. That's right. And we shouldn't do that, because everyday lies protect us a little bit. So in the episode, everyone lies twice a day. The lie researcher Bella de Paolo from the University of California has found out that this is now, so to speak, the average. Of course, there are also pathological lies that cannot be lied to at all. But these are now the fewest. Autonomous lies, there are lies, also a little bit of the social kit in our society. Because when you, the boss, the boss or the mother-in-law, the father-in-law, would say how you actually find her or her. Ah, that's right. It can also start later, I understand. And still, many people believe that they somehow get along, that someone lies, so that you can somehow see the lies of someone else, right? Yes, that's probably because this thought is simply difficult to bear, that lies do not have to be praised for it, right? It's the opposite of our justice. So, we rather believe that lies are somehow fabricated. I'll say it like this, the good side of it is that we still believe in the good in the human being. So, if we were now in such a half-eight position all the time and would draw every spoken detail into doubt, then we would really march through the world with full mistrust. Yes, and that's not fun either. No. So, we rather believe the majority of what you are telling us. To be honest, we are not in a criminal series here and we have to do it permanently with punishments we want to carry out. So, in our normal everyday life, we don't even lie so often, like I said, maybe once or twice a day. And then maybe it's still a compliment, right? But is the new fraud good? I think that's what you're talking about. It was a nice conversation. Really? No, really. That's the advantage of this podcast. You can be sure that you won't lie to us here. Of course, we also make mistakes, but usually we will correct them. Maybe he will guide us all the way. Then please write to us if you find something. Then you can lead us here. Julia Trams from Quarkstein. Thank you. It's almost over now. I already told you about the train hotel in the restaurant in Möbelhäusern, in supermarkets and also on many public places. There are free WLANs that you can log in and then you can log into the Internet for free. That's the question. Is that also safe now? In the past, these public WLANs were often used as places where frauds and fraudsters would tumble and want to dig up your data. And that's why Klaus from the Quarks community also reported to us. He asks us how to surf actually safe. Does it make sense to set up a VPN tool? If there is only an unguided WLAN, how safe is the "guided WLAN" when, for example, the password is hanging everywhere in the restaurant? Do you have tips that we, good scientists, can also look into online banking without having to worry that someone will read with us? We take care of the questions, or we do that together with Michael Stein, scientist and technical journalist at the Quarks team. Michael, how is that with public WLANs? Are they still as insecure as they used to be? Are they still as important as a few years ago? Because we now have all our data volume. Well, it has already changed a lot. With mobile phone it is now so fast that we basically no longer really miss WLANs. Most of us will probably have a flat rate on your smartphone with limited data volume, but in any case have decent volume. But of course that can also be used. Of course. Or what if you are on vacation for example, and then maybe there is another country, maybe there is a problem with mobile phone access at that point, maybe you want to go online with a tablet or notebook and that is too complicated for you with the hotspot and so on. So under a line, if there is a free WLAN available, then it is probably much more likely to save data volume on your smartphone. But the use of a public WLAN has always been and is still not without a risk in the opposite. Where are there even public WLANs at all? I just came out of the vacation, I was on my way with the train, there it is already working, sometimes better, sometimes worse, because I don't know, we will still fall into a hotel somewhere else. Yes, hotel and train are very typical WLANs. You have to register, you also have to have a password and so on. There are also a lot of free parks, of course on campsites and in fast food restaurants, in supermarkets, I didn't know that until now, but it is actually like that. And also in drug markets, by the way, there are public WLANs. There are also WLANs that are very open, for example in some inner cities. You don't need a password yet. Especially such WLANs in inner cities, they are usually offered by city agencies. They are important, also to enable digital participation. Also people with little money can then go there on the Internet. That is often in the vicinity of the town hall, for example. They can get information, for example, they can also get help from authorities, and much more. Okay, that's kind of a good idea at first. I think it's good that you can do that on the other hand. You can ask yourself why they also make supermarkets or free parks. Do they have similar ideas behind them? Do you feel comfortable when there are free WLANs? Yes, that is certainly a reason. Another and probably even more important reason is that I can be tracked and tracked by WLANs as a customer. So which ways do I go to the store? Where do I stay? And above all, who am I actually? Do I actually buy online? So I am now there at the store, but basically I am already known online by the respective dealer. The dealer then has even better ways to identify with me if I use his app. You know the question, do they have the Rewe or Kaufland or whatever app? Do you always get this question asked on the box? And if I still use the WLAN of the supermarket, then the app can be exchanged directly with the network of the market data. So this combination of the supermarket app and that, so to speak, also use your own WLANs. In the free park it is very similar. The dealer observes which attractions we use, where we stay, where we go along and so on. But in the free park, of course, they also do that to be able to better predict which attractions are particularly popular. When do staff have to be strengthened there and so on. Okay, you can somehow understand that they do it if it is possible. It is quite practical. On the other hand, for us it is also a bit spooky, to be honest. Every step, every movement is controlled. But that is probably different in campsites or hotels, or are we also tracked there? Well, hotels actually do that in the first line as a service for their guests. The risk is there, a bit different. There you are then with many, many others at the same time on the same network and can be spironed in the case of doubt. Have you forgotten that, for example, some orders can be shared on the laptop with other family members now? About these shared functions that you might have set up once, because it is not so practical in your own network. But now you can suddenly read and copy the content. By the way, using criminals is a very simple trick. The so-called evil twin, i.e. the evil twin, is a hotspot. Yes, it is so similar to the hotspot of a hotel, maybe just a number or a bookshelf. That is why there are always analyses of various security software providers, which always determine that. Okay, they do that of course, to make sure that they have a great protection software and that we should buy them right away. But that means that it is really a scenario that we can encounter. Then there is some data deep somewhere in the same hotel or on the same campsite and take pictures. Yes, the hotspot is then operated by criminals in another room or other mobile phones at the campsite. And who then connects with this hotspot, then opens his smartphone, his tablet, his laptop for the criminals. That is, the data can then be fished out. They can then be copied in Windows and we can also be observed how we can contact our customer from our hotel room in our bank account. And then we can also read the access data. And we don't notice anything of it, because we will still be connected to the internet via the hotspot of criminals. But we are still in the right place on the internet, but it is observed. So it's a really good feeling, it doesn't leave anything to me at all, doesn't there any solution to use the advantage? Then somehow you offer such a WLAN on the way, or just in the hotel room. So I don't know, can you help a solution, VPN or something like that? So the question just came to us from the cross community. Yes, a solution could be a solution, but then it really has to be used properly and also be sufficiently high. So on both sides, so to speak. And that's exactly what you can't see from the outside and can only be judged very poorly as an expert or not an expert. How good is that really solved? And with other technical solutions, for example, VPN, so Virtual Private Network, you then have to trust the respective providers that you have chosen. If you have a good, trustworthy provider, then that could be a solution. But such a VPN, you have to want it first, you have to understand what it does first, you have to set it up, it has to work, and that's not always the case. And depending on the doubt, you also have to pay money, right? Exactly. That means, what is the solution, rather than using a foreign WLAN, to be safe? Yes, please, that is, yes, that is of course a solution, of course. So maybe really rather use enough data volume, book and then actually use it outside or on vacation. A WLAN should only be used where the provider really knows and knows how safe the network is. And socially, for the digital participation, maybe also appropriate data rates, for people with little money, a safe alternative to public WLAN hotspots. So, and with that, dear Klaus, your questions should hopefully be answered. If you have a question that we can answer for you, then please write to us or send us a message about how we can achieve ourselves. You will find that directly around the corner in the show notes. Thank you, Michael Stein. You're welcome. Katrin has also reported to us. She writes, "Thank you very much for all the great episodes. I find it super impressive how you do it. Also heavy and uncomfortable topics, easy and sympathetic to chat. You always improve my mood and my general knowledge. First of all, thank you dear Katrin, we like to do it. And Katrin also sent us a topic idea. We will take care of it and discuss it in the next video. Again, the memories, show notes are a good starting point for you. If you want to write or talk to us, you can find the contact options. Take a look at it in general. There is also more information about today's topic. I am Sebastian Sontag. Bye.
