People use less information than they think to make up their minds

Abstract

A world where information is abundant promises unprecedented opportunities for information exchange. Seven studies suggest these opportunities work better in theory than in practice: People fail to anticipate how quickly minds change, believing that they and others will evaluate more evidence before making up their minds than they and others actually do. From evaluating peers, marriage prospects, and political candidates to evaluating novel foods, goods, and services, people consume far less information than expected before deeming things good or bad. Accordingly, people acquire and share too much information in impression-formation contexts: People overvalue long-term trials, overpay for decision aids, and overwork to impress others, neglecting the speed at which conclusions will form. In today’s information age, people may intuitively believe that exchanging ever-more information will foster better-informed opinions and perspectives—but much of this information may be lost on minds long made up.

Significance

People readily categorize things as good or bad, a welcome adaptation that enables action and reduces information overload. The present research reveals an unforeseen consequence: People do not fully appreciate this immediacy of judgment, instead assuming that they and others will consider more information before forming conclusions than they and others actually do. This discrepancy in perceived versus actual information use reveals a general psychological bias that bears particular relevance in today’s information age. Presumably, one hopes that easy access to abundant information fosters uniformly more-informed opinions and perspectives. The present research suggests mere access is not enough: Even after paying costs to acquire and share ever-more information, people then stop short and do not incorporate it into their judgments.

The danger of absolute thinking is absolutely clear

Here is an excerpt:

There are generally two forms of absolutism; ‘dichotomous thinking’ and ‘categorical imperatives’. Dichotomous thinking – also referred to as ‘black-and-white’ or ‘all-or-nothing’ thinking – describes a binary outlook, where things in life are either ‘this’ or ‘that’, and nothing in between. Categorical imperatives are completely rigid demands that people place on themselves and others. The term is borrowed from Immanuel Kant’s deontological moral philosophy, which is grounded in an obligation- and rules-based ethical code.

In our research – and in clinical psychology more broadly – absolutist thinking is viewed as an unhealthy thinking style that disrupts emotion-regulation and hinders people from achieving their goals. Yet we all, to varying extents, are disposed to it – why is this? Primarily, because it’s much easier than dealing with the true complexities of life. The term cognitive miser, first introduced by the American psychologists Susan Fiske and Shelley Taylor in 1984, describes how humans seek the simplest and least effortful ways of thinking. Nuance and complexity is expensive – it takes up precious time and energy – so wherever possible we try to cut corners. This is why we have biases and prejudices, and form habits. It’s why the study of heuristics (intuitive ‘gut-feeling’ judgments) is so useful in behavioural economics and political science.

But there is no such thing as a free lunch; the time and energy saved through absolutist thinking has a cost. In order to successfully navigate through life, we need to appreciate nuance, understand complexity and embrace flexibility. When we succumb to absolutist thinking for the most important matters in our lives – such as our goals, relationships and self-esteem – the consequences are disastrous.
