From The Leaning Tower illusion: a new illusion of perspective Frederick A. A. Kingdom, Ali Yoonessi, Elena Gheorghiu Perception. 2007. 36(3):475-477:
Consider the photograph in [above image] of the Petronas twin towers in Kuala Lumpur. Both towers are physically vertical, but in the two-dimensional projection their corresponding outlines are not parallel but converge as the towers recede into the distance. Our knowledge of perspective however compensates for this and leads us to perceive the inclinations of the two towers veridically.
From The Leaning Tower illusion (cont’d):
Our knowledge of perspective however compensates for this and leads us to perceive the inclinations of the two towers veridically. It follows that if the corresponding outlines of a pair of physically identical, receding objects are parallel in the two-dimensional projection, the objects cannot be physically parallel but, instead, must be diverging as they recede from view. This is clearly what we perceive in [above image], where the right-hand tower has been replaced with a copy of the one on the left. Now the corresponding outlines are parallel, and the two towers appear to diverge . . . .
From The Leaning Tower illusion (cont’d)
The illusion is not restricted to towers photographed from below, but works well with other scenes, such as the tram lines in above image. What the illusion reveals is not a failure of perspective per se, but the tendency of the visual system to treat two side-by-side images as if part of the same scene. However hard we try, we seem unable to see the two photographs of the Leaning Tower in figure 1 as separate, albeit identical, images of the same object. Instead, our visual system regards the images as the `Twin Towers of Pisa’, whose two-dimensional projection leads to the `correct’ interpretation that one tower is leaning more than the other.

Despite cultural progress in reducing overt acts of racism, stark racial disparities continue to define American life. This conference considers what emerging social science can contribute to the discussion of race in American law, policy, and society. The conference will explore how scientific evidence on the human mind might help to explain why racial equality is so elusive. This new evidence reveals how human mental machinery can be skewed by lurking stereotypes, often bending to accommodate hidden biases reinforced by years of social learning. Through the lens of these powerful and pervasive implicit racial attitudes and stereotypes, the conference, designed to coincide with the launch of the book “Implicit Racial Bias Across the Law”, examines both the continued subordination of historically disadvantaged groups and the legal system’s complicity in the subordination.
The conference will bring together scholars, judges, practitioners, and community leaders to explore the issues surrounding implicit racial bias in law and policy. It will begin with a compelling overview of the social science. What does science teach us about automatic biases? And what do we still not know? Leaders in the areas of criminal justice, housing law and policy, education, and health care will then present overviews of the impact of implicit bias in their fields. Attendees will hear federal judges’ and leading scholars’ perspective on implicit bias claims in the courtroom and hear experts’ assessment of the future of implicit bias in the law. A lively afternoon session will include simultaneous break-out sessions and roundtable discussions of specific implicit bias related topics. Audience participation will be welcomed and encouraged. The conference will close with a discussion of setting a forward looking and collaborative implicit bias agenda.

At the Fifth Project on Law and Mind Sciences Conference,“The Psychology of Inequality” (Harvard, 2011) , Laura Kubzansky made a fascinating presentation, titled “Stress and Reslience: Pathways to Social Disparities in Health.” The video of her presentation is above. Here is a short description:
This presentation discusses stress and resilience as important mechanisms by which social disparities influence health. It considers how being stressed or resilient is shaped by social environment, and whether these processes influence health.
