摘要

在本研究中,我们记录了一种新的预测偏差,我们称之为“未来即现在”(FIN)偏差。具体来说,我们表明人们倾向于相信未来会反映现在,即使这种信念是没有根据的。也就是说,人们高估了现在发生的事情在未来发生的可能性,即使(已知的)未来结果的明确概率与这种信念相矛盾。这似乎是由锚定和(不充分的)调整过程驱动的,即对未来的最初信念受到当前环境的严重影响,然后一旦了解到未来结果的概率,随后的信念就没有得到充分调整。在9项研究中(雇用超过3800名参与者),我们在各种预测背景下证明了FIN偏差,表明它在激励兼容设置中表现出来,并提供证据支持锚定和(不充分的)调整机制。

The 'Future Is Now' Bias: Anchoring and (Insufficient) Adjustment When Predicting the Future from the Present
In the present research, we document a novel forecasting bias, which we term the “future is now” (FIN) bias. Specifically, we show that people tend to believe that the future will mirror the present, even when such a belief is unfounded. That is, people overestimate the chances that whatever is happening now, will happen in the future, even when the (known) explicit probabilities of future outcomes contradict such a belief. This appears to be driven by an anchoring and (insufficient) adjustment process, whereby initial beliefs about the future are heavily influenced by the present circumstances, and then subsequent beliefs are not sufficiently adjusted once the probabilities of future outcomes are learned. Across nine studies (employing over 3,800 participants), we demonstrate the FIN bias in a variety of forecasting contexts, show that it manifests in incentive compatible settings, and provide evidence in support of an anchoring and (insufficient) adjustment mechanistic account.
