▁factor ▁above , ▁ 1   −   K , ▁has ▁the ▁effect ▁of ▁completely ▁ign oring ▁conflict ▁and ▁att rib uting ▁any ▁mass ▁associated ▁with ▁conflict ▁to ▁the ▁null ▁set . ▁This ▁combination ▁rule ▁for ▁evidence ▁can ▁therefore ▁produce ▁counter int uit ive ▁results , ▁as ▁we ▁show ▁next . ▁ ▁Example ▁producing ▁correct ▁results ▁in ▁case ▁of ▁high ▁conflict ▁The ▁following ▁example ▁shows ▁how ▁D emp ster ' s ▁rule ▁produces ▁intuit ive ▁results ▁when ▁applied ▁in ▁a ▁preference ▁fusion ▁situation , ▁even ▁when ▁there ▁is ▁high ▁conflict . ▁ ▁Suppose ▁that ▁two ▁friends , ▁Alice ▁and ▁Bob , ▁want ▁to ▁see ▁a ▁film ▁at ▁the ▁cinema ▁one ▁evening , ▁and ▁that ▁there ▁are ▁only ▁three ▁films ▁showing : ▁X , ▁Y ▁and ▁Z . ▁Alice ▁express es ▁her ▁preference ▁for ▁film ▁X ▁with ▁probability ▁ 0 . 9 9 , ▁and ▁her ▁preference ▁for ▁film ▁Y ▁with ▁a ▁probability ▁of ▁only ▁ 0 . 0 1 . ▁Bob ▁express es ▁his ▁preference ▁for ▁film ▁Z ▁with ▁probability ▁ 0 . 9 9 , ▁and ▁his ▁preference ▁for ▁film ▁Y ▁with ▁a ▁probability ▁of ▁only ▁ 0 . 0 1 . ▁When ▁combining ▁the ▁prefer ences ▁with ▁D emp ster ' s ▁rule ▁of ▁combination ▁it ▁turns ▁out ▁that ▁their ▁combined ▁preference ▁results ▁in ▁probability ▁ 1 . 0 ▁for ▁film ▁Y , ▁because ▁it ▁is ▁the ▁only ▁film ▁that ▁they ▁both ▁agree ▁to ▁see . ▁ ▁D emp ster ' s ▁rule ▁of ▁combination ▁produces ▁intuit ive ▁results ▁even ▁in
