We use big data methods to investigate how decision-making might depend on future sightedness (that is, on how far into the future people's thoughts about the future extend). In study 1, we establish a link between future thinking and decision-making at the population level in showing that US states with citizens having relatively far future sightedness, as reflected in their tweets, take fewer risks than citizens in states having relatively near future sightedness. In study 2, we analyze people's tweets to confirm a connection between future sightedness and decision-making at the individual level in showing that people with long future sightedness are more likely to choose larger future rewards over smaller immediate rewards. In study 3, we show that risk taking decreases with increases in future sightedness as reflected in people's tweets. The ability of future sightedness to predict decisions suggests that future sightedness is a relatively stable cognitive characteristic. This implication was supported in an analysis of tweets by over 38,000 people that showed that future sightedness has both state and trait characteristics (study 4). In study 5, we provide evidence for a potential mechanism by which future sightedness can affect decisions in showing that far future sightedness can make the future seem more connected to the present, as reflected in how people refer to the present, past, and future in their tweets over the course of several minutes. Our studies show how big data methods can be applied to naturalistic data to reveal underlying psychological properties and processes.
我们使用大数据方法来研究决策如何依赖于未来远见(即人们对未来的思考能延伸到多远的未来)。在研究 1 中,我们通过表明美国各州公民的未来视野相对较远(反映在他们的推文中),比未来视野相对较近的州的公民承担的风险更小,在人口水平上建立了未来思维与决策之间的联系。在研究 2 中,我们分析了人们的推文,以确认未来视野与个人决策之间的联系,表明未来视野较长的人更有可能选择更大的未来奖励而不是较小的即时奖励。在研究 3 中,我们表明随着人们推文所反映的未来视野的增加,冒险行为会减少。未来视野对决策的预测能力表明,未来视野是一种相对稳定的认知特征。这一含义在对超过 38,000 人推文的分析中得到了支持,表明未来视野既有状态特征,也有特质特征(研究 4)。在研究 5 中,我们通过提供证据表明未来视野可以通过影响决策的潜在机制来影响决策,表明未来视野可以使未来与现在更紧密地联系起来,这反映在人们在推特上如何在几分钟的时间内提到现在、过去和未来。我们的研究表明,大数据方法如何可以应用于自然数据,以揭示潜在的心理特性和过程。
