1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Why do individuals tend to discount bad news when making judgements about the likelihood of future events? In this short review, we explore recent research findings regarding this frequently observed and replicated phenomenon - optimism bias - with particular attention on how this bias affects the way individuals update or revise their beliefs. We begin by highlighting five interrelated frameworks for understanding optimism bias (utility maximization, active inference, dual systems, cognitive immunity, predictive processing). We then examine findings from affective and clinical domains that indicate that people with depression and other psychiatric disorders, as well as acutely sad or anxious individuals, have dampened optimistic bias when updating beliefs in response to good news. Finally, we consider the neural underpinnings of these phenomena through the free energy principle and discuss implications for clinical interventions and future research.
