ENTRY 3: Identify Bias
Item 1
Vốn gia đình khá giả, lại mới sinh được con trai nên chị Lam và nhà chồng rất cưng bé Tùng Anh. Quần áo, đồ chơi, hay thực phẩm cho Tùng Anh ăn hàng ngày đều phải là đồ ngoại. “Từ hồi mang bầu Tùng Anh, tôi đã xem rất nhiều bài báo nói về vụ sữa nhiễm melamine, hoa quả thì chất lượng kém, dùng nhiều chất kích thích. Hơn nữa, Tùng Anh lại là cháu cưng của cả nhà, ai cũng mong muốn bé được phát triển toàn diện, khỏe mạnh, giỏi giang. Nên từ khi sinh ra, thứ gì cho bé cũng phải mua hàng ngoại”.
- Type of Bias: Discrimination
- Analysis: She expresses preference to the goods, which are imported from foreign countries. She makes an assumption that foreign products is much good than domestic products, so she does not like using domestic ones (prejudice). Therefore, her only buying foreign imports shows discrimination to domestic goods (prejudice in action).
Item 2
- Types of Bias: Discrimination
- Analysis: the security guard does not allow the man to go through, just because he looks ugly and poor (his suitcase and clothes). This is discrimination against human right. People have right to be behaved equally which does not depend on the appearance, social position, jobs, etc.
Item 3: Chickens Prefer Beautiful Humans
Authors at the Stockholm University
Methods
- Chickens: The experimental animals were six chickens (Gallus gallus domesti-cus), of which four females. The animals had experience with the experimental setup (pecking visual stimuli on a computer screen), but not with tasks involving faces.
Testing: During a test trial, a randomly chosen face (there are 7 different faces) was shown for 10 s, and the number of pecks to it was recorded. No reinforcement was given on test trials. Testing continued until all animals had received at least four presentations of each of the test faces.
- Humans: Fourteen undergraduate students in biology (seven females) participated in the study for course credits.
Testing: The students were asked to rate, in random order and on a scale from 0 to 10, all faces how desirable would it be to go on a date with the portrayed person. Each face was shown alone on a computer screen, until the subject rated it. The total scores collected by each face were transformed into relative scores, which allowed comparison with animal data.
Result: the face, which the chicken pecked is the face, which people liked most.
- Type of Bias: Assumption
- Analysis:
+ Firstly, the subjects for research are not large enough to lead to a conclusion. They carried out the research with only six chickens, which belonged to the same species (Gallus gallus domesti-cus) and fourteen students, who studied in the same course. Choosing subjects is not random.
+ Secondly, there is no evidence to prove that chickens pecking something mean that they like it
