title: Laws about bodily damage originate from shared intuitions about the value of body parts

description: From the biblical lex talionis to the medieval wergild system and modern
 workers’ compensation laws, laws about bodily damage may originate from
 neurocognitive mechanisms that capitalize on an enduring regularity:
 Different body parts vary in their incremental contributions to human
 functionality. To evaluate this hypothesis, we conducted a preregistered
 study with materials based on five legal codes from highly diverse
 cultures and historical eras: the Law of Æthelberht (Kent, c. 600 CE), the
 Guta lag (Gotland, c. 1220 CE), and workers’ compensation laws from the
 United States, the Republic of Korea, and the United Arab Emirates; and
 614 laypeople from the United States and India. The data indicate ordinal
 agreement in the values attached to body parts by ancient and modern
 lawmakers, as well as by laypeople in the United States and India. The
 observed agreement across time, space, and levels of legal expertise
 suggests that laws about bodily damage originate from shared intuitions
 about the value of body parts.

In each condition, participants were asked to imagine a specific background event (e.g., in the Difficulty condition, losing a body part in an accident) and then answered a question about each of various body parts. Thus, condition is a between-subjects variable, while body parts are a within-subjects variable. The questions asked about each of various body parts in each condition were as follows, with the imagined background event in brackets. (1) Difficulty: \[You lose various body parts in an accident]. How difficult, if at all, would it be for you to keep doing the things that you need to do in order to be a functioning person? (2) My Anger: How much anger, if any, would you feel toward your acquaintance if, because of their recklessness, you lose various body parts? (3) My Gratitude: \[You lose body parts in an accident but someone is able to re-attach them or restore their functionality]. How much gratitude, if any, would you feel toward that person? (4) Their Anger: \[Because of recklessness, you cause an acquaintance of yours to lose body parts]. How much anger, if any, do you think your acquaintance would feel toward you? (5) Their Gratitude: \[An acquaintance of yours loses body parts in an accident, but then you are able to re-attach them or restore their functionality]. How much gratitude, if any, do you think your acquaintance would feel toward you? (6) Price: \[Imagine there is a country with a market for body parts]. What are the market prices of various body parts in this market? (7) Compensation: \[Imagine that you are a lawmaker; your task is to determine how much money, if any, an employee should receive as compensation if they lose a body part in a workplace accident]. How much money, if any, should employees be compensated with? | n/a | | Participant # | n/a | | Country | n/a | | Condition | n/a | | Sex | female-male | | Big toe | Range for Difficulty, My Anger, My Gratitude, Their Anger, and Their Gratitude conditions: 0-100;
