The precise reason for this difference is unknown, but Allcott (2011) speculated that receiving a handwritten emoticon as part of a study sponsored by a university might have a larger effect on behavior than receiving a printed emoticon as part of a mass produced report from a power company.
Sababu hasa ya tofauti hii haijulikani, lakini Allcott (2011) alikisia kwamba kupokea kihisia kilichoandikwa kwa mkono kama sehemu ya utafiti uliofadhiliwa na chuo kikuu kunaweza kuwa na athari kubwa kwenye tabia kuliko kupokea kihisia kilichochapishwa kama sehemu ya ripoti inayotolewa kwa wingi kutoka kwa kampuni ya nguvu.
