100 Humans Season 1 Episode 7 Can You Trust Your Senses?

In the seventh episode of 100 Humans, titled "Can You Trust Your Senses?", the participants explore the limitations and accuracy of their sensory perception. The episode commences with Dr. Melanie examining how humans perceive time through her time machine experiment. She assigns the participants two different tasks that will test their time perception skills.

The first task involves the participants having to hit a button as soon as they hear a sound. The sound is played at different intervals, and the participants must try and hit the button at the exact moment they hear the sound. This task proves to be quite challenging, as some participants struggle to distinguish between the different sounds played. Others struggle to hit the button at the right time, while others succeed in nailing the task.

The second task involves the participants having to estimate the duration of a minute without looking at a clock. The participants are quite confident that they can accomplish the task, but the results prove to be a bit surprising. Some of the participants are too fast and end up estimating a minute too quickly. Others are too slow and end up going over a minute. This experiment shows the human brain's inability to consistently estimate time accurately.

In the next experiment, the participants are tasked with guessing the weight of an object. Dr. Melanie brings in a box which contains random objects. The participants are required to lift the box and estimate its weight based on their perception. The experiment shows that humans tend to overestimate the weight of objects based on their size. Some of the small objects they estimate to be heavier, while larger objects are estimated to be lighter.

The third experiment in the episode is centered around taste perception. Dr. Alie brings out a new food item called a "Yum Dozer" - it is a strange-looking metallic gadget that the participants will use to give their taste buds a unique experience. They need to put the gadget on their tongue and use the handlebars to stimulate different taste receptors. Some participants identify sweet, salty, and sour tastes, while others could not identify any of the tastes, indicating that their taste buds are not as sensitive.

In the final experiment, the participants participate in a virtual reality game where they are required to navigate through a maze using their senses of touch and smell. They have to use their sense of touch to find objects and use their sense of smell to determine whether the object found is pleasant or unpleasant. The participants found the game to be quite challenging, as they were tasked with using their senses in an unfamiliar way.

The episode concludes with the participants having an interesting debate on whether or not it is possible to trust one's senses. Some argue that their perception shapes how they encounter the world; hence they can not discredit their senses. On the other hand, some argue that their senses deceive them and can not be trusted fully. The episode proves to be both informative and entertaining, making the audience aware of the limitations and accuracy of their sensory perception.
