The recent emergence of machine-manipulated media raises an important societal question: How can we know whether a video that we watch is real or fake? In two online studies with 15,016 participants, we present authentic videos and deepfakes and ask participants to identify which is which. We compare the performance of ordinary human observers with the leading computer vision deepfake detection model and find them similarly accurate, while making different kinds of mistakes. Together, participants with access to the model’s prediction (...) are more accurate than either alone, but inaccurate model predictions often decrease participants’ accuracy. To probe the relative strengths and weaknesses of humans and machines as detectors of deepfakes, we examine human and machine performance across video-level features, and we evaluate the impact of preregistered randomized interventions on deepfake detection. We find that manipulations designed to disrupt visual processing of faces hinder human participants’ performance while mostly not affecting the model’s performance, suggesting a role for specialized cognitive capacities in explaining human deepfake detection performance. -/- .

Nincs még egy délkelet-ázsiai ország, mely oly markáns hatást gyakorolt volna a huszadik század történelméről kialakult képükre, mint az egyesítésének 40. évfordulóját idén ünneplő Vietnami Szocialista Köztársaság. Ezt persze több évtizedes háborús szenvedéseinek és az amerikai tömegkultúra ezt nemritkán sajátosan közvetítő, de mindenképpen globális kisugárzással bíró üzeneteinek „köszönheti”.1 Vietnam viharos történelmi közelmúltja máig rányomja bélyegét a vele kapcsolatos képünkre, jóllehet, az említett 1975. évi – az északi és déli országrész egyesülésével járó – újjászületés óta itt sem állt meg az idő. (...) A Lengyelországnál alig nagyobb Vietnam 2015-re a Föld 13. legnépesebb országa lett, és korábbi elképesztő szegénységének enyhítésében is – bár európai szemmel szerénynek tűnhető, de – határozott javulást könyvelhet el.2 Napjainkban – ahogy azt a távol-keleti nemzetközi kapcsolatok alakulásánál megszokhattuk – a Kínai Népköztársaság hatalmi súlyának fokozódása és regionális ambíciói helyezték új megvilágításba a „legmagyarabbnak” tekintett3 délkelet-ázsiai nép lehetséges szerepét. Ez egyszersmind az alapdilemmát is azonnal eszünkbe juttatja: Vietnam múlt századi tragédiáját a vele kapcsolatos nagyhatalmi ambíciók idézték elő. Igaz, az ország bizonyította ellenálló képességét, és a 21. századra változott valamelyest a szereposztás is, Délkelet-Ázsia hosszú távú jövője a nemzetközi rendszerben továbbra is bizonytalan. Az alábbiakban számvetésre vállalkozunk Vietnam helyzetéről és lehetséges pozícióiról korunk vezető hatalmainak kelet-ázsiai játszmáiban. (shrink)

How children seek knowledge and evaluate claims may depend on their understanding of the source of knowledge. What shifts in their understandings about why scientists might disagree and how claims about the state of the world are justified? Until about the age of 41/2, knowledge is seen as self-evident. Children believe that knowledge of reality comes directly through our senses and what others tell us. They appeal to these external sources in order to know. The attainment of Theory of Mind (...) (ToM) at this age is commonly seen as the significant shift in development in understanding disagreements in knowledge claims. Children attaining ToM understand that someone exposed to incorrect or incomplete information might have false beliefs. Disagreement, then, is still attributed to objective sources of knowledge. The current study examines the later developing Interpretive Theory of Mind (iToM) as the basis for children’s understanding of how people with access to the same information might disagree and what this means for how to provide justification for a knowledge claim. Fourteen 2nd graders with the most iToM responses to four tasks and 14 with the fewest iToM responses were selected from a larger sample of 91. In analyses of interviews about a story in which two experts make different claims about a scientific phenomenon, those in the high iToM group noted subjective perspective and processes as the source of disagreement and suggested the need for investigation as the means to knowing. In contrast, those in the low iToM group mostly could not explain the source of disagreement and held that knowledge is acquired from external sources. A comparison of the interviews regarding the science story 2 years later allows for a qualitative description of the development. Those in the low iToM group showed more general recognition of subjective and constructive processes in knowing whereas those in the high iToM group identified interpretive processes and the relativity of perspectives with implications for how observations were conducted and interpreted. Only those in the high iToM group referred to the importance of evidence as a basis for knowledge claims at either point in the study. (shrink)

Quality of Zionism`s formation Written by: A.M. Abstract One of the most important discussions in every school of thought is the subject of recognizing the enemies against the given school. Every being in the world should know their enemies in order to be able to secure their survival and provide the necessary means of defend against the enemies. Even the animals follow the same rule; no animal was trapped by the hunter except when it acted ignorantly. Concerning this subject, Imam (...) Khomeini Says no freeman officially recognizes Israel. The Quranic verse (82, surah: Ma`edeh) explains the subject of knowing the enemy and prioritizes it as, “Latajiddana Ashad Al-Nas” The first important enemy is the Jews and if one day the Quran would change the first important enemy changed. Any mention of the Jews in the Quran should be interpreted as the Zionism. The second important enemy is “Al-Ladina Ashraku” which means the polytheists. Another Quranic verse says that the Christians are also the Muslims` enemies, “Wa lan Tarza ankel Yahud Wa la Nasara Hatta Tattabe`a Mellatahom Qol Inna Hada Allah Wa laen Ittabaat Ahwa`ahom Bad Al-Ladi Jaaka Min Al- Elme Ma laka Men Allah-e Men Waliye Wala Nasir” meaning that the Jews and Christians will never be satisfied with you [so that you surrender to their wants] and follow their [distorted] religion. Say: Guidance is only the God`s guidance! And if you follow their desires, after becoming aware of it, there will be neither divine guardians nor any companions for you. (Surah: Baqareh, Verse 120). This article has mostly dealt with the basic formation of the Zionism. The subject has been divided and discussed in 4 categories, namely civil Zionism, Zionism in economy, policy, and religion. The article studies the importance of the Middle East in the viewpoint of “Lord Rochild” and the issue of laying the groundwork for controlling the Middle East as the best option for founding the Jew government. The Zionism`s four mentioned aspects were effective and aimed at creating a powerfull united Zionist government and later and as the result of these efforts the Israel promised state was founded. The author points to the serious problems of Zionism and indicates that the Post-Zionism, who had entered the scene to solve these problems, could not succeed in doing this mission. چگونگی شکل‌گیری و پیدایش صهیونیزم//Quality of Zionism`s formation//تأسیس الصهیونیة و ظهورها Keywords: Zionism, Economic, Political, Cultural and Religious Zionism, Israel, Rothschild, Instantly.
