Experiment Instructions

You are part of an expedition studying aliens on a distant planet. On this planet, aliens extract a blue mineral that is highly valuable to human scientists. Your team plans to hire some of these aliens to mine the mineral for research purposes.

Here is a figure of the blue mineral:

Experiment Instructions

Not all aliens are equally good at mining. Some are highly skilled, while others are less effective. To decide which groups to hire and how much to pay them, your task is to estimate the mining ability of different alien populations.

Experiment Instructions

Alien groups differ in several features. One key feature is eye color. Each group has a unique eye color: red, yellow, and purple.

In this study, your captain has assigned you to focus on red-eye aliens and estimate their mining ability.

Experiment Instructions

Another key feature that distinguishes alien groups is their living area. Regardless of their eye color (red, yellow, or purple), all aliens inhabit one of two landscapes: Desert and Forest.

Therefore, one may consider the mining ability of aliens based on whether they are desert aliens or forest aliens, regardless of eye color.

The two landscape icons indicating whether an alien is a desert aliens or forest alien is as follow:

Desert (left): Sandy terrain with sparse flora.
Forest (right): Landscape largely defined by dense jungle.

Experiment Instructions

All red-eye aliens live in a desert. This living area is characterized by vast sandy terrain with sparse vegetation, rolling dunes, and scattered rock formations. Steady winds shape the landscape, creating distinctive patterns and geological features throughout the area.

Experiment Instructions

Your team has established a clear standard for measuring mining capability.

Every time an alien tries to mine the blue mineral, they either succeed and collect one or fail and get nothing. For example, an alien who succeeds 5 times out of 10 attempts collects 5 minerals. To evaluate a group's mining skill, your team uses a simple index: how many minerals, on average, the aliens in that group collect per 10 attempts.

Experiment Instructions

Your first step is to learn about the mining capability of red-eye aliens.

To help you estimate this group's mining capability, you will see evaluations from 3 of your teammates. Each teammate independently reviewed the 10-attempt mining records of 5 red-eyed aliens. They have summarized their findings by providing a group average.

Each teammate's report follows this format: "Based on my assessment, red-eyed aliens collect an average of X minerals per 10 attempts." This value X may include decimals, as it represents the group average rather than the results of a single alien.

By clicking "next", you will start viewing your 3 teammates' reports. Each report will be shown 10 seconds.

The report from your teammate is as follows:

"Based on my assessment, red-eyed aliens collect an average of minerals per 10 attempts."

Which record do you think was selected by the current participant to describe the number of minerals the red-eye aliens extracted in 10 attempts

Loading records of the next participant...

You have finished reviewing the reports from your 3 teammates. Based on your impression, please estimate how many minerals red-eye aliens collect per 10 attempts on average.

Please indicate your response: -

0 10

Experiment Instructions

In addition to reviewing your teammates' reports, you now have the opportunity to observe the actual mining behavior of 5 red-eye aliens.

Loading records of the next alien...

Experiment Instructions

You will now provide your estimation of red-eye alien's mining capability again. You will see a series of choices. On each trial, two mining records will be displayed. Based on what you learned from other participants and what you observed yourself to decide which record better reflects how many minerals red-eye aliens typically extracted in 10 attempts on average.

Taking into account everything you have seen so far—the teammates' reports and the individual records—what is your estimate for the average number of minerals red-eyed aliens collect in 10 attempts?".
