Støydeteksjon Sveits
Hva denne siden viser
Tenk deg at bensinprisen stiger med 30 prosent — men kveldsnyhetene nevner det ikke. Eller det motsatte: rentene står stille, men dekningen eksploderer. Begge deler er målbare. Og begge sier noe om kvaliteten på offentlig kringkasting.
Suppression Index sammenligner det som skjer i den virkelige verden med det som vises på TV. Dataene kommer fra offisielle kilder — den sveitsiske sentralbanken, det føderale statistikkbyrået, MeteoSveits, trafikkulykkesstatistikk. Sendetidene er hentet fra over 19 000 transkriberte SRF-sendinger.
Når en reell utvikling er betydelig men dekningen er liten, kaller vi det undertrykkelse: et viktig tema blir forsømt. Når dekningen er stor men den reelle utviklingen er liten, kaller vi det støy: noe blåses opp utover det faktaene rettferdiggjør.
Begge kan ha legitime årsaker. Ikke all undertrykkelse er tilsiktet, og ikke all støy er manipulerende. Men et mønster over år og programformater er ikke tilfeldig. Det er systematisk atferd — og det er nettopp det grafene nedenfor avslører.
Disse målingene er permanente. De oppdateres månedlig, men grunnprinsippet endres ikke: dekning bør følge virkeligheten, ikke omvendt. Enten du er forsker eller bonde — hvis melkeprisene stiger og TV-en tier, vises det her.
The Suppression Index S measures whether Swiss public television (SRF) coverage is proportional to real-world developments. It compares official statistics (SNB, BFS, MeteoSwiss, ASTRA) with the airtime share devoted to each topic.
Reading guide: Grey bars = outcome change (left axis), red line = airtime share (right axis). When bars are high but the line is low → suppression (topic is ignored). When the line is high but bars are low → noise (disproportionate coverage).
