I think that it was fascinating what I learned about today. How it is that we relied too much on our sense perception to shape our world, although it main function was to only help us survive. How without it that we could feel so lost, and scared, but yet, with blind people, they are able to cope with it or maybe with animals like dogs and cats that use other sense of them. Also, it was interesting how sometimes our sense perception could jump to a conclusion so quickly, or fill in the gaps of something we see so quick and we, without questioning it, trust it right away, which could cause negative consequences in society. What I think I could relate to my life are the optical illusions within the books, it's quite impressive of how changing a point of view may change the whole big picture.


I've learned more about sense perception. I think that for our badge, we could set up the fallibility of sense perception. We could show the audiences pictures of people and then ask a question related to that and they would then base on the question to choose out the picture of a person that seem related the most to the question. This I think would then show how much we relied on our sight and how sometimes it could be so wrong. The things that went well today that I think we were able to get hold of an idea of what sense perception is and we were able tohave some abstract ideas of how our presentation are gonna go. However, we haven't got our own knowledge question yet and because of that, we haven't actully got to decided how we are going to present it to the class, and these are the 2 things that didn't go quite well for today.


We managed to do a lot of thing. We were able to decided what we would do next class for our presentation, we have had specific items that we could show to the class to make clear how each theories of reality would be beneficial for us in each condition. For the presentation next class, I would have to make main points of what I would say during the play we set up, I would need to try and extend that main point and keep it within the Common realism. In my opinion, the great part about our play that we are going to present is that we would show the audience of how common realism usually out compete scientific realism, as there are more people using it. We managed to did this by using 2 common realism as opposed to only 1 scientific realism in the play


I think that for the goal of today presentation for the group is that we would be able to present as we have planned, and hope that our time doesn't exceed the time given and that we could express our question efficiently to the class. For a personal goal, I would say that I hope I'm calm during the presentation and will be able to deliver it successfully to the class.


Our group primary aim for this project was to present to our class the 2 different Theories of Reality, which is common realism and scientific realism, and how in different situation we would need to use different theories of reality to be able to perceive the situation and to gain new knowledge. So, we set up a play to present to the class. Marco was a teacher of a class, Eduardo was the scientific realism student while me and Jeremy was the common realism students. The reason we used 2 common realism students and only 1 scientific realsim was because that in our world, common sense realism tend to be more popular amongst people, so it is something that we would also want to show the class this fact

Reflection Journal

I think that throughout this project with the group, I had a chance to learn more about sense perception, how each Theories of reality works and how we should use them. From the starting point, when we didn't have much idea of how to plan the presentation out, what is our knowledge question that we would base on to make a presentation and present it to the class to when we were able to make a knowledge question of our own, and from there, forming a play to help present it too the whole class. Also, I enjoyed the project a lot, in my opinion, we were able to set up a great play, and managed to send the ideas of what we want to the audience. Moreover, I have noticed that sometimes our senses can be very unreliable, for example the book mentioned of eyes witness testimony, which was also mentioned in another IB class of mine, psychology. We saw a case of a man, named Ronald Cotton, who was falsely convicted for raping a 22-year-old girl Jennifer Thompson and was sentenced to prison. The main point was when Thompson was shown by the police officer with photos of man who look-a-like her description. She chose Ronald picture and when asked to identify who she thinks commited the crime, she also pointed at Ronald, however, in a later interview, she mentioned that it was after she pointed to him, the officer next to her confirmed to her that he was the one she chose in the picture, concreting her idea that Cotton committed the crime. I was able to notice here also that, this has connection to a key point in the chapter, which is: "We usually distinguish between appearance and reality by using a second sense to confirm the evidence of the first, or by appealing to coherence or the testimony of other people" and in here, she used the testimony of an officer that she chose the same guy, to concrete her knowledge.

To what extent is our understanding of the world shaped by our sense perception?

In my own opinion, from our sense perception, we would experience the world in many different ways and thus, would than shaped our own world in may different ways. As for example, in Isaac Lidsky talk, I could see that how his depriviation in his eye vision than give him illusion that we don't usually have. As he said: "The sales manager I spotted in the store was a mannequin, reaching down to wash my hand, I suddenly saw that it was a urinal I was touching, not a sink, when my fingers felt the true shape." This I think is a hard evidence for how a person relied a lot on their vision and when the vision is suddenly lost, we tend to connect the feeling of what the hands feel to the vision we have of them earlier, however, this change the way our inner world is shape, as we needed to learn how to differentiate some characteristic of one object to another as there are objects that share some siimliar characteristic and using our hand to feel it, we may mistakenly identify it. He also mentioned how the way we see can change the way we feel and the way we feel can change the way we see, which means that it is shaping our world differently. I also found a Ted talk of Daniel Kish, who was blind at a very young age and used sonar to navigate the world around him. He said at the end of his presentation that his world was quite difference, as he said, rather than us, our eyes could just see in a definite range, his was rather different which was a 360 degree view and he would be able to listen to even the smallest sound made by a person within the theatre, or here what people were talking about through some walls. Those are the things that I think would show that our sense perception take up a large portion of how our understanding of the world is shaped.

Lenses of Perception

Oreo scientific realism:

-When I taste the Oreo, I’m getting a sweet taste, indicating the presence of carbohydrates. Just think about it, it’s a source of short-term energy. If they’re consumed in moderation, how can they be considered unhealthy…I mean, everything is technically organic, made from living atoms and comprising carbon.

Common sense- Don’t think of the oreo in terms of chemistry and biology, just think about the fact that they’re cookies. Sweetness indicates sugar, but I’ve learned from past experiences that added sugar is simply unhealthy and even addicting. I know that eating too many will hurt my diet and decrease my consumption of nutritious food.

Common sense 2- Come on, it’s a cookie. Since when was a processed chocolate cookie considered food for athletes right before practice?

Scientific realism- You might be right. Now that I combine my thinking with logic, it does make sense that Oreos aren’t all that great. I guess they can increase chances of diabetes, which I realize is a negative health repercussion. Thanks for helping me out here, I’ll try to avoid them as much as possible.

Wow, this strawberry is great. But dang it, we just agreed that this sugary sweet taste corresponds to unhealthy food and snacks.

Common sense- Strawberries are fruits, of course they’re healthy. They’re directly organic, no processed added sugar.

Common sense 2- A strawberry’s a strawberry, it’s a good food whichever way you see it. Other knowers have all told me the same.

Scientific realism- Each strawberry is comprised of the monosaccharide fructose, but with the help of insulin it’s stored the liver as glycogen for later use. This is starting to make sense, thanks for helping me out with my diet guys!

Optical illusion 1 (lines):

Common sense- These lines are definitely slanted, isn’t it so straightforward! My senses are delivering, are you telling me my eyes are lying?

Scientific realism-Remember interpretation is a huge part of perception. Here’s a ruler, those lines are straight for a fact, just measure them. You’ll see that to observe the reality to the best of our abilities, you must learn to view only the relevant lines and then make observations.

Common sense- Wow, that’s pretty solid evidence. This is just incredible, can’t believe it’s the reality.

Teacher- Here’s a box now, tell me if you guys see anything

Common sense- Well, there’s a gray box, with a gray color much lighter in the bottom portion.

Common sense- I mean, it’s a skillfully drawn box.

Scientific realism- Wait guys, this is another optical illusion. You see, by adding the bright strip in the middle, the continuity was disrupted and the contrast between light and dark gray on the bottom square is highlighted. Take out the line, the effect disappears.

You taught me great lessons with food, but sometimes being straightforward deceives the senses into false creations. Be careful.

Teacher Great class discussions. So today we learned common sense and scientific realism have benefits and limitations as the situation changes, showing how the theories of reality must work in conjunction, along with confirmation with reason and intuition, and other such WOKs. Therefore, we can agree that senses primary function is not to give image of reality, but to provide tools for survival.
