Cognition, Perception, and Knowledge

• Cognition: The processes a system uses to acquire, store, represent, use, and respond to signals/information from the body and environment (e.g., body signals, environmental stimuli).

• Cognition: The mental operations that support people’s acquisition and use of knowledge.

• Conscious Cognition: Thought processes we are aware of, such as reasoning, decision-making, and problem-solving.

• Non-conscious Cognition: Mental processes that occur automatically, without conscious awareness, such as perception, memory retrieval, and habitual actions.

• All aspects of cognition are... INTERTWINED

• Top-down Processing: Processes (i.e., knowledge-based; e.g., thought and motivations) influence what we detect, attend to, and perceive!

Caesar Cipher: Formal Representation

Plain alphabet: P = {sequence of plaintext letters}. Key: k ∈ {i | 0 ≤ i ≤ 25}. If k = 25, the shift maps a → z, b → a, and so on. Encryption: E(p) = (p + k) mod 26. Decryption: D(c) = (26 + c − k) mod 26.

Attacking the Caesar Cipher

Common methods to solve or attack a Caesar (shift) cipher include:

1. Brute force: Try all possible keys (0–25) and inspect the results.
2. Statistical (frequency) analysis: Use letter frequency distributions of the language to infer likely mappings.

Frequency Analysis: Basic Idea

Certain letters appear more frequently than others in a given language. By comparing ciphertext letter frequencies to natural language frequencies, you can match ciphertext characters to likely plaintext

Cognitive Biases & Self-Reflection

Common cognitive biases can hinder objective judgment:

• Ignorance Assumption: Assuming disagreement stems from a lack of information.
• Idiocy Assumption: Attributing disagreement to a lack of understanding or narrow perspectives.
• Evil Assumption: Attributing disagreement to malicious intent.

The implications of these biases are discussed, emphasizing the need for self-reflection to avoid constructing infallible, self-serving narratives.

Types of Research Misconduct

• Fabrication (Illegitimate creation of data): Fabrication is the act of conjuring data or experiments with a belief of knowledge about what the conclusion of the analysis or experiments would be, but cannot wait for the results possibly due to timeline pressures from supervisor or customers.

• Falsification (Inappropriate alteration of data): Falsification is the misrepresentation or misinterpretation, or illegitimate alteration of data or experiments, even if partly, to support a desired hypothesis even when the actual data received from experiments suggest otherwise. Falsification and fabrication of data and results hamper engineering research and cause false empirical data to percolate in the literature, wreck trustworthiness

Chapter 5: Uncovering Systemic Injustice

Bryan Stevenson begins a deeper investigation into Walter McMillian’s case, uncovering significant misconduct by law enforcement and the prosecution. He discovers that Walter was placed on death row before his trial, an unusual and cruel treatment that underscored the racial bias in the case. Stevenson learns about the prosecution’s reliance on coerced and fabricated testimony from Ralph Myers and Bill Hooks. He faces hostility and intimidation from local officials as he works to challenge the wrongful conviction.

Key Figures and Their Roles in the Case

Walter McMillian

Walter was placed on death row even before being convicted, a rare and punitive measure. His alibi—being at a fish fry with dozens

Support Vector Machines (SVM)

A support vector machine is a supervised method for classification or regression that seeks a boundary in a high-dimensional space which separates classes with the widest possible margin. The training process involves choosing a boundary that maximizes the distance to the nearest training points, known as support vectors. When data are not perfectly separable, slack variables can be introduced to allow some misclassifications or margin violations while balancing margin maximization and classification accuracy. A kernel is a special function that effectively maps data into higher-dimensional spaces without doing the mapping explicitly; it lets the support vector machine handle nonlinear relationships by measuring...
