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

Previous studies have demonstrated that individuals can utilize the wisdom of crowds, known as 'the wisdom of the inner crowd'. This requires answering the same question multiple times and averaging the estimates. Although several methods have been proposed to achieve more accurate estimates, its efficacy remains relatively low. Therefore, this study proposes a method that assembles multiple independent methods to simulate the wisdom of the inner crowd effect. Particularly, our method instructs participants to provide estimates five times. Through a behavioural experiment, we confirmed that our method can produce the wisdom-of-innercrowd effect. Moreover, we found that our method produced more accurate estimates than a method that required participants to estimate five times without specific instructions. Furthermore, mathematical modelling demonstrated that the effectiveness of our method was greater than that of 1.5 persons. In sum, this study proposes a method to improve daily estimates.
