Summary
Forensic bitemark identification remains debated, lacking consensus on admissibility despite 150 years of development. Modern analysis and new techniques offer potential for evaluating this complex dental evidence.
Area of Science:
- Forensic Odontology
- Legal Medicine
- Evidence-Based Science
Background:
- Forensic bitemark identification involves a three-stage process: bitemark examination, suspect dentition evaluation, and evidence interpretation.
- The process inherently involves significant uncertainty due to incomplete or ambiguous data.
Purpose of the Study:
- To review modern bitemark analysis using Daubert's criteria.
- To assess bitemark analysis in the context of reasoning under uncertainty.
Main Methods:
- Literature review of bitemark analysis and legal standards.
- Evaluation of modern scientific approaches to bitemark evidence.
Main Results:
- Despite over 150 years of development, a consensus on the admissibility of bitemark evidence is lacking.
- Recent scientific efforts aim to introduce novel techniques and assess the reliability of bitemark evidence.
Conclusions:
- Forensic bitemark identification continues to face challenges in establishing a consensual basis for evidence admissibility.
- Emerging scientific research presents new perspectives for evaluating the evidential value of bitemarks.

287
Appearance is a multidimensional aspect of self-presentation that encompasses observable attributes such as clothing, grooming, speech, and nonverbal behavior. These elements are often strategically managed to align with socially constructed expectations in different settings. For instance, individuals tailor their appearance during job interviews, social gatherings, or athletic events to meet the perceived norms of those environments.Contextual Adaptation and Social SignalsThe research...

Aligning actions are communicative strategies individuals employ to maintain social harmony and preserve personal identity in the face of potential disruptions to social norms. These actions are particularly important in managing social impressions when one's behavior might be seen as inappropriate, incompetent, or morally questionable.Types of Aligning ActionsThe three principal types of aligning actions are disclaimers, accounts, and apologies.DisclaimersDisclaimers are preventive; they are...

In a study where individuals posing as strangers offered compliments and proposed casual sex to students, the responses differed significantly based on gender. Not a single woman accepted the proposal, while 70% of the men agreed. This outcome provides a useful scenario to explore through the lens of evolutionary psychology and social learning theory, highlighting the diverse perspectives on human sexual behaviors.

The discussion of bullying highlights the problem of witnesses not intervening to help a victim. This is a common occurrence, as the following well-publicized event demonstrates. In 1964, in Queens, New York, a 19-year-old woman named Kitty Genovese was attacked by a person with a knife near the back entrance to her apartment building and again in the hallway inside her apartment building. When the attack occurred, she screamed for help numerous times and eventually died from her stab wounds.

31.2K
Deindividuation is a form of social influence on an individual’s behavior such that the individual engages in unusual or non-normal behavior while in a group setting. Why? Because in these group settings, the individual no longer sees themselves as an individual anymore, disinhibiting their behavior and personal restraint.

Behavior is a product of both the situation (e.g., cultural influences, social roles, and the presence of bystanders) and of the person (e.g., personality characteristics). Subfields of psychology tend to focus on one influence or behavior over others. Situationism is the view that our behavior and actions are determined by our immediate environment and surroundings. In contrast, dispositionism holds that our behavior is determined by internal factors (Heider, 1958).
