Eyewitness testimony and its veracity presents problems for juries and judges, according to the University of California's Dr Elizabeth Loftus. She tells Eve Ash that this intersection of psychology and law has revealed that the more confident a witness, the more they are believed even if their memories are mistaken. More than 300 people, such as Steven Titus (misidentified as a rapist) have been convicted through faulty or false memories. The problem is compounded when zealous detective coach witnesses, or when false and distorted memories are "implanted". People sometimes cling to a mistaken belief, even when the evidence shows they are wrong. Show Less

Eve Ash discusses why people tell lies with the University of Massachusetts Amherst's Professor Robert Feldman, a specialist in psychological and brain sciences. He has studied lying for many years and observes that (1) all people tell lies in different situations; (2) many are not truthful on their resumes and in job interviews; (3) sometimes people confabulate to fill memory gaps caused by stressful or traumatic conditions. In crime situations, he explains that false memories occur, and people's eagerness to find a culprit sometimes leads to the wrong person being convicted. You can't always tell a liar from their physical cues (e.g. excessive blinking, looking away). This can cause deception bias and investigations clouded by tunnel vision. Dr Feldman and Eve Ash discuss the case of Sue Neill-Fraser, convicted and jailed for murder in Tasmania in 2010. Show Less

Eve Ash talks to Professor Robert Feldman (University of Massachusetts Amherst) about his research for the book "The Liar in Your Life": He reveals that we all lie at different times, there are many types of lies ranging from the unconscious to lies of commission, and that people often lie within the first ten minutes of meeting someone. We lie to create an impression, we lie because we are anxious, we make up narratives to fill gaps in our memories. We have a "truth bias" in as much as we don't want to believe another person might be lying. Lies create spiral effects ("You lie, I lie"). We might be suspicious of liars, but we also tend to forgive them. Lies lead to inauthenticity in relationships. People compartmentalize lies and can live with them for many, many years. Show Less

People sometimes lie for a reason and will exaggerate to enhance their prestige in the eyes of others. People having secret affairs tell lies; this was the situation for Eve Ash's mother who lied for years about Eve's biological father. Eve's subsequent investigation revealed her real father, and how he was built into her story, although her mother never admitted the truth. Discovering her personal story has led Eve to forgive her mother's deception. Show Less

Photosynthesis supplies all oxygen for life, and it began in the sea. Amazingly, it all relies on one basic kind of chemical reaction that was achieved over two billion years ago by cyanobacteria, and cyanobacteria living as endosymbionts in plants and phytoplankton still produce almost all our oxygen. This programme tells the story of the cyanobacteria, how they changed our planet and are involved in supporting its many life forms. We look at the four major groups that photosynthesise in the sea: cyanobacteria, eucaryote phytoplankton (microalgae), seaweeds (macroalgae), and seagrasses. These groups are responsible for supplying around half the oxygen we breathe—so in terms of understanding the processes that keep us alive, this is a very important story. Show Less
