In the latest episode of The Science of Personality, Ryne and Blake are joined by Melvyn Payne, Commercial Director at Advanced People Strategies out of the UK, to talk about potential to performance. The word potential gets thrown around a lot in HR and talent management circles, but potential on its own really means nothing if it doesn't translate to performance. As the commercial director of one of Hogan's top international distributors at APS, few people in the world of Hogan know more about this topic than Melvyn. 

In the latest the latest episode of The Science of Personality, Ryne and Blake talk about authenticity. We've all heard the saying before: “Be your authentic self.” In fact, common wisdom for years has suggested that authenticity is a good thing, and few have doubted the merits of that “wisdom.” But what if we were to tell you this might actually be the opposite and could actually hurt your career? Ryne and Blake address that and so much more in this episode.

In the latest episode of The Science of Personality, Ryne and Blake talk about toxic employees and the affect they have on organizations across the globe. We've all experienced it: the colleague who brings the mood down, the boss who thrives on chaos, or the team member whose negativity drains the energy from the room. These "everyday" toxic behaviors create stress, hamper productivity, and leave us feeling demoralized. But what may not be immediately apparent is the significant hidden cost they carry.

In the latest episode of The Science of Personality, Ryne and Blake are joined by Zsolt Feher, Hogan's vice president of business development, to talk about charisma in politics. For centuries, charismatic politicians have had a significant advantage when it comes to assuming leadership roles.

In this episode, we'll talk about some of the more notable charismatic politicians throughout history, what personality characteristics they have in common, and whether they actually are effective leaders. 

In the latest episode of The Science of Personality, Ryne and Blake are joined by Douglas Kenrick, PhD, professor of psychology at Arizona State University, to talk about evolutionary psychology.

In the latest episode of The Science of Personality, Ryne and Blake discuss a topic that everyone has at least been subjected to, if not been a victim of, and that is scammers. Whether by phone, email, or other means, scammers use a variety of methods to access sensitive data or to make a quick buck. So, the question is: why do people fall for these schemes? What makes us so vulnerable to these vultures who seem to seek us out on an almost daily basis? 

In the latest episode of The Science of Personality, Ryne and Blake are joined by world-renowned personality psychologist and good friend of the podcast, Adrian Furnham, PhD, to talk about a recent paper he authored on the personality characteristics of people who prefer to work from home. So many people across the globe found themselves working from home once the Covid pandemic shook the world of work, and many continue to do so five years later due to the popularity of it. But why was it so popular? Why did so many people cling to it long after most of the world returned to normal? Well, a lot of it could be explained by personality and that's what we're going to talk about today.

In the latest episode of The Science of Personality, Ryne and Blake are joined by Allan Church, PhD, cofounder and managing partner at Maestro Consulting and former SVP of global talent management at PepsiCo, to talk about the impact of personality on careers.

In the latest episode of The Science of Personality, Ryne and Blake are joined by Krista Pederson, Hogan's managing director of Asia Pacific, to talk about the recent launch of Hogan's Global Leadership Effectiveness Study, a groundbreaking research study aimed at identifying the characteristics shared among effective leaders.

We  explore all of that and so much more in this episode.

In the latest episode of The Science of Personality, Ryne and Blake talk about social influence and why people change their behaviors because of social interactions. We've all been guilty at some point in our lives of allowing others to influence our decisions, whether consciously or subconsciously. But what underlying psychological factors are at play? Why do we allow these external forces to change the way we think, feel, and behave? 

In the latest episode of The Science of Personality, Ryne and Blake are joined by Ty Wiggins, PhD, the lead of Russell Reynolds Associates' CEO & Transitions Practice, to talk about CEO transitions and his latest book, The New CEO. Although there might be numerous people out there who might consider themselves experts on this topic, Ty is one of only a handful of people globally who actually has a PhD in senior leadership transitions. So, you would be hard-pressed to find anyone with more knowledge and expertise on this particular subject.Order The New CEO here: https://www.russellreynolds.com/en/microsite/the-new-ceo/order

In the latest episode of The Science of Personality, Ryne and Blake are joined by Larry Martinez, PhD, associate professor of psychology and the A. Dale Thompson Endowed Chair of Leadership at the University of Texas at Arlington, to talk about the psychology behind the Salem Witch Trials. For those in the US and beyond, this is probably something you're somewhat aware of, but did you know that it's highly likely that those accused of and executed for crimes of witchcraft in early American history actually weren't witches at all? So, what happened? What was going on in the psyche of early-day American settlers that led them to believe the “offenders” were witches? We cover this and so much more in the second and final spooky season episode of 2024.

In the latest episode of The Science of Personality, Ryne and Blake talk about a newer topic that is on the minds of many Hogan clients, partners, and distributors, and that is the issues that could arise from a “nice” corporate culture and how to combat them. In theory, having a nice culture sounds ideal on the surface, but does it really deliver results and is it the best model in today's world? 

In the latest episode of The Science of Personality, Ryne and Blake are joined by Kyle Cermak, director of business development on Hogan's solutions partners team, to talk about team development in the modern age. It should come as no surprise that work has changed significantly in recent years, as many more of us have transitioned to a hybrid working model or working from home entirely. But that doesn't mean teams have disappeared. It just means that they must operate differently, and team development is ultimately the key to overall team effectiveness and performance in this new world of work.

In the latest episode of The Science of Personality, Ryne and Blake speak with Jean Twenge, PhD, professor of psychology at San Diego State University, about managing Gen Z in a special live episode of the podcast. It is easy to assume that baby boomers, Gen X, millennials, and Gen Z all differ significantly from each other as each generation entered the workforce under much different conditions. However, when it comes to personality, age often plays a powerful role in how individuals behave at work. Now that Gen Z is firmly established within the global workforce, does the same pattern hold true?

But what really determines who is successful and who is not? 

In the latest episode of The Science of Personality, Ryne and Blake talk about the differences between IQ and EQ. From a historical perspective, the term IQ, short for intelligence quotient, was coined in 1912 by psychologist William Stern. Conversely, the term EQ, short for emotional quotient or the more commonly used emotional intelligence, wasn't really popularized until 1995 when Daniel Goleman released his book titled Emotional Intelligence. But that's just the history of the terms. In all actuality, IQ and EQ have existed for all of human history. In this episode, Ryne and Blake dig a little deeper into what IQ and EQ actually are, how they are developed, and how they're measured.

In the latest episode of The Science of Personality, Ryne and Blake discuss a hot topic that is sure to impact the assessment industry: people seeking assessment advice from ChatGPT. It's widely known by now that AI and large language models like Chat GPT have a wide range of useful applications, such as drafting emails, writing essays, summarizing information, and creating efficiencies in the workplace. But how good are these tools at giving people advice on how to respond to items on a personality assessment? 

In the latest episode of The Science of Personality, Ryne and Blake are joined by Kelsey Klausing, Hogan's director of solutions partners, to take an inside look at delivering feedback for Hogan's assessments. To do so, Kelsey simulates a Hogan feedback session with Blake as the subject using his actual Hogan results.

The outcome of this convergence is currently unknown, but a recent paper authored by Peter and his colleagues offers a deeper look at what this might look like, which we discuss in this episode.

In this episode, Erin explains why skills-based hiring is so important and outlines the steps organizations can take to implement a more robust talent acquisition strategy.
