In a small housing complex lived three neighbors, Chandra, Olumide, and Gretchen, who had formed a close-knit community. One day, Chandra baked a batch of cookies and placed them in a shared common area with a note that simply read, "Enjoy!" Unbeknownst to Chandra, Olumide had a mild allergy to nuts but, nonetheless, Olumide happily helped himself to a cookie, not noticing the scattered almonds baked into them. An hour later, Gretchen saw Olumide eating the cookies, but she was unaware of his allergy. Gretchen, however, did not partake as she was not fond of sweets. Later that day, Chandra mentioned to Gretchen in passing that she had baked almond cookies. Gretchen, remembering Olumide eating the cookies but not being aware of his allergy, thought nothing of it. The next day, Olumide mentioned to Chandra while chatting that the cookies were delicious, although he felt a bit strange afterwards, but he didn't associate this with his nut allergy because he was unaware that the cookies contained almonds. Chandra thanked him but did not mention the almonds, thinking that Olumide wouldn't have eaten the cookies if he were allergic. The following week, Chandra decided to bake another batch of cookies, this time choosing to make them nut-free since she wanted to try a new recipe. She left them in the common area again with the same type of note. Reason everything regarding what each person knows about the cookies, their ingredients, and Olumide's condition.
In this scenario, several interactions are happening simultaneously concerning the knowledge possessed by Chandra, Olumide, and Gretchen about the cookies and Olumide's allergy. Starting with Chandra, she knows that she baked almond cookies initially and placed them in the common area. However, she does not know about Olumide's allergy to nuts, and because Olumide gave her positive feedback without mentioning his allergy, she believes he has no issue with the ingredient.

Olumide, on the other hand, ate the cookies unaware of their almond content, which is something Chandra does not know. After feeling strange, he did not connect his reaction to the cookies, so he holds a belief that the cookies were delightful and harmless, when in fact, they caused his adverse reaction. Additionally, Olumide has no knowledge about Chandra's plan to change the cookie recipe to exclude nuts, nor does he have any reason to suspect that the cookies he ate contained almonds or that the future batch would be different.

Gretchen is aware that the first batch of cookies contained almonds, as this was mentioned by Chandra. She also saw Olumide eat these cookies but is unaware of his nut allergy, and therefore, she does not know that Olumide's consumption of the cookies could have been harmful to him. She also does not know that Olumide felt strange afterwards, nor is she aware that Chandra has decided to make the next batch of cookies nut-free. Thus, her knowledge is limited to the almond content of the first batch, which she considers non-threatening information.

Each individual holds beliefs that are not fully informed by the complete picture--Olumide is ignorant of the almonds' presence in the cookies, Chandra is ignorant of Olumide's allergy and believes that the cookies had no negative effect on him, and Gretchen is unaware of the potential harm due to Olumide's unrecognized allergy and is also uninformed about the recipe change.

When Chandra bakes the new batch of nut-free cookies, Olumide may eat them with no adverse effects this time, which could strengthen his belief that the previous cookies were also harmless. If Chandra learns about Olumide's allergy before he has the chance to eat the nut-free cookies, she may express concern and reveal the previous batch's ingredients to him, leading to a re-evaluation of Olumide's belief about the initial batch. Meanwhile, unless Gretchen is informed of Olumide's condition, her understanding will remain disconnected from the potential danger Olumide was in when he ate the almond cookies.
