飲食對人嘅健康有深遠影響:人食得多得滯會肥,所以佢哋食嘢嗰陣要食得適量;而且淨係食得適量係唔夠嘅-例如生果同蔬菜提供到維他命 C 呢種重要嘅維他命,而呢種維他命係肉食提供唔到嘅,所以人除咗要食適量,仲要食得均衡,攝取到嗮人體需要嘅各種營養。喺 2010 年代起,有唔少行為經濟學研究者同營養學工作者合作諗計,想用輕推鼓勵人均衡飲食[3][14]。
設定好嗮啲嘢之後,班研究者就暗中派人觀察研討會嘅出席者,數住每位出席者屬邊條隊同埋攞咗咩嘢食。事後佢哋就對攞到嘅數據做分析,發覺(簡化講)出席者顯著比較大機率會攞佢哋第一眼望到嘅嘢食-枱 A 嘅出席者比較大機率會攞煙肉同有芝士嘅蛋,而枱 B 嘅出席者就比較大機率會攞生果同低脂肪乳酪。基於呢個發現,班研究者就作出提議,主張「將啲健康嘢食擺喺就手或者樣眼嘅地方」能夠做一種輕推,用嚟鼓勵食自助餐嘅人食多啲健康嘢食,有助體重管理等嘅工作[3]。
一門領域會想左右人嘅行為,就表示佢哋有機會用到輕推。好似係工作場所(泛指畀員工做嘢嘅空間,包括辦公室同周圍嘅設施)嘅設計噉,唔少管理工作者都想將工作場所設計成「有利於令員工有效率做嘢」嘅樣;例如喺 2017 年就有管理學者撰文,分析 Google 點樣設計佢哋嘅工作空間,用工作場所入面嘅輕推令啲員工開會、編寫計劃、做嘢同交流知識嗰陣效率更高,包括[16]-
有醫療研究者運用信任呢個概念:人係種有社會性嘅動物,一個人會著重佢同其他人建立嘅關係,當中信任係關係嘅一個重要元素;如果阿 A 信任阿 B,通常係因為阿 B 喺過去一路有關照阿 A 或者以第啲方法對阿 A 好,而阿 A 亦會因而更加願意接納由阿 B 提供嘅資訊(肯信嗰件資訊係真確)。於是佢哋就做出以下噉嘅思考[19]:
