Du lär dig att förstahandsinformation alltid är mer tillförlitlig än andrahandsberättelser. Boken är för dig som vill förstå informationsflödet i dagens samhälle och hur det påverkar vår verklighetsuppfattning. Genom att läsa den kommer du att bli mer kritisk och medveten om källor och informationens kvalitet.\u003c\/p\u003e\u003cdiv class=\"product__accordion accordion quick-add-hidden\" style=\"background-color: #edeae3;\"\u003e\u003cdetails id=\"Details-collapsible_tab_1\"\u003e\u003csummary role=\"button\" aria-expanded=\"false\" aria-controls=\"ProductAccordion-collapsible_tab_1\" class=\"accordion__summary\"\u003e\u003cdiv class=\"summary__title flex\" style=\"padding: 0 2rem 0 2rem;\"\u003e\u003ch3 class=\"accordion__title inline-richtext\" style=\"line-height: 2.5rem;\"\u003eFörlagets information\u003c\/h3\u003e\u003c\/div\u003e\n\u003csvg aria-hidden=\"true\" focusable=\"false\" class=\"icon icon-caret\" viewbox=\"0 0 10 6\"\u003e\u003cpath fill-rule=\"evenodd\" clip-rule=\"evenodd\" d=\"M9.354.646a.5.5 0 00-.708 0L5 4.293 1.354.646a.5.5 0 00-.708.708l4 4a.5.5 0 00.708 0l4-4a.5.5 0 000-.708z\" fill=\"currentColor\"\u003e\u003c\/path\u003e\u003c\/svg\u003e\u003c\/summary\u003e\u003cdiv class=\"accordion__content rte\" id=\"ProductAccordion-collapsible_tab_1\" style=\"padding: 0 2rem 0 2rem;\"\u003e\n\u003cp\u003eDoes information really diminish? Looking at social media, information definitely grows. New content is endlessly added. But, given this enormous growth in content what is diminishing then? Let’s illustrate: You witness an incident and you describe it to somebody, who in turn passes it further, etc. Your original account swells the more it’s retold. It gets more details and color, perhaps it even gets juicier. But the information about what has really happened diminishes at each step. That’s the Law of diminishing information (LDI):\u003c\/p\u003e\n\u003cp\u003eSecond hand information is never better than firsthand.\u003c\/p\u003e\n\u003cp\u003eAs Chico Marx said: Who Ya Gonna Believe, Me or Your Own Eyes? Exemplified in the old-fashioned news media, a reporter is telling you what he sees for himself. This information tends to be true. Information given by social media can be true too, but more likely by accident.\u003c\/p\u003e\n\u003cp\u003eThe LDI is statistical in nature. You tell someone the PIN code is 1234. The listener hears it as 1254, and repeats that. But the next recipient hears it as 1234 again. Now the correct information is restored. Yet with overwhelming probability, any mishearing likely leads to more errors, than to correction. We end up with a series of random numbers, giving no information whatsoever about the original PIN.\u003c\/p\u003e\n\u003cp\u003eThe same statistical principle works with the mechanics of a large number of particles. In physics, LDI is called the second law of thermodynamics. In quantum mechanics this statistical phenomenon is called decoherence. Claude Shannon’s communication theory builds on a special case of LDI, where information is measured in entropy (i.e. disorder). When information is measured in Fisher information (i.e. sharpness) LDI leads to Schrödinger’s wave equation in quantum mechanics. LDI also applies to automatic control theory, to von Neumann’s theory of games, and to Einstein’s special relativity theory.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/details\u003e\u003c\/div\u003e\u003cdiv class=\"product__accordion accordion quick-add-hidden\" style=\"background-color: #edeae3;\"\u003e\u003cdetails id=\"Details-collapsible_tab_1\"\u003e\u003csummary role=\"button\" aria-expanded=\"false\" aria-controls=\"ProductAccordion-collapsible_tab_1\" class=\"accordion__summary\"\u003e\u003cdiv class=\"summary__title flex\" style=\"padding: 0 2rem 0 2rem;\"\u003e\u003ch3 class=\"accordion__title inline-richtext\" style=\"line-height: 2.5rem;\"\u003eData om boken\u003c\/h3\u003e\u003c\/div\u003e\n\u003csvg aria-hidden=\"true\" focusable=\"false\" class=\"icon icon-caret\" viewbox=\"0 0 10 6\"\u003e\u003cpath fill-rule=\"evenodd\" clip-rule=\"evenodd\" d=\"M9.354.646a.5.5 0 00-.708 0L5 4.293 1.354.646a.5.5 0 00-.708.708l4 4a.5.5 0 00.708 0l4-4a.5.5 0 000-.708z\" fill=\"currentColor\"\u003e\u003c\/path\u003e\u003c\/svg\u003e\u003c\/summary\u003e\u003cdiv class=\"accordion__content rte\" id=\"ProductAccordion-collapsible_tab_1\" style=\"padding: 0 2rem 0 2rem;\"\u003e\n\u003cbr\u003e\u003cdiv style=\"padding: 0 20px 0 20px; border: thin solid #000000;\"\u003e\u003cp style=\"font-size: smaller;\"\u003e\u003cb\u003eBindning:\u003c\/b\u003e Förlagsband.\u003cb\u003eÅr:\u003c\/b\u003e Utg. 2025. \u003cb\u003eOmfång:\u003c\/b\u003e 256 s. \u003cb\u003eISBN:\u003c\/b\u003e 9789190027042. \u003cb\u003eSpråk:\u003c\/b\u003e Engelska\u003c\/p\u003e\u003c\/div\u003e\n\u003cbr\u003e\u003cdiv style=\"padding: 0 20px 0 20px; border: thin solid #000000;\"\u003e\u003cp style=\"font-size: smaller;\"\u003e\u003cb\u003eFörfattare:\u003c\/b\u003e \u003ca href=\"\/search?q=title:K%C3%A5hre+Jan\"\u003eKåhre, Jan\u003c\/a\u003e \u003cbr\u003e\u003cb\u003eTitel:\u003c\/b\u003e \u003ca href=\"\/search?q=title:The+Law+of+Diminishing+Information\"\u003eThe Law of Diminishing Information\u003c\/a\u003e \u003cbr\u003e\u003cb\u003eFörlag:\u003c\/b\u003e \u003ca href=\"\/search?q=vendor:Vulkan\"\u003eVulkan\u003c\/a\u003e \u003cbr\u003e\u003cb\u003eGenre:\u003c\/b\u003e \u003ca href=\"\/search?q=Samh%C3%A4lle+och+samh%C3%A4llsvetenskap\"\u003eSamhälle och samhällsvetenskap\u003c\/a\u003e \u003cbr\u003e\u003cb\u003eArtikelnr:\u003c\/b\u003e 540581250\u003c\/p\u003e\u003c\/div\u003e\n\u003c\/div\u003e\u003c\/details\u003e\u003c\/div\u003e\u003chr\u003e\u003cp\u003e\u003cstrong\u003e\u003cem\u003eThe Law of Diminishing Information\u003c\/em\u003e\u003c\/strong\u003e av \u003cstrong\u003eJan Kåhre\u003c\/strong\u003e hittar du under genren \u003cstrong\u003eMedievetenskap\u003c\/strong\u003e inom \u003cstrong\u003eSamhälle \u0026amp; kultur\u003c\/strong\u003e i kategorin \u003cstrong\u003ePolitik \u0026amp; samhällsvetenskap\u003c\/strong\u003e.
