What is behind the so-called Flynn Effect - the pattern of rising IQ scores around the world?
IQ is rising in many parts of the world. What's behind the change and does it really mean people are cleverer than their grandparents?
It is not unusual for parents to comment that their children are brainier than they are. In doing so, they hide a boastful remark about their offspring behind a self-deprecating one about themselves. But a new study, published in the journal Intelligence, provides fresh evidence that in many cases this may actually be true.
The researchers - Peera Wongupparaj, Veena Kumari and Robin Morris at Kings College London - did not themselves ask anyone to sit an IQ test, but they analysed data from 405 previous studies. Altogether, they harvested IQ test data from more than 200,000 participants, captured over 64 years and from 48 countries.
Focusing on one part of the IQ test, the Raven's Progressive Matrices, they found that on average intelligence has risen the equivalent of 20 IQ points since 1950. IQ tests are designed to ensure that the average result is always 100, so this is a significant jump.
We are in the midst of a paradigm shift that, at times, can be disconcerting. But if we embrace the new worldview that science gives us, we stand to be far more effective managers. The place to start is with an understanding of three fundamental discoveries about how the brain works.
Do you know of anyone who has suppressed bad news to preserve their career or reputation?Or told the boss what they wanted to hear instead of the truth?Or overlooked a red flag to preserve the sense of harmony in the workplace?Most often ego is catalogued as 'good' or 'bad', but what if it's simply about your relationship with yourself?

Habits of mind Uncertainty can’t be solved with pat procedures; it takes new habits of mind to lead the possible. In our experience, three such habits stretch the capabilities of leaders and help them not only to lead the possible but also to delight in it. ~ McKinsey

He describes leading as the art of influencing and motivating people to perform in a manner to achieve a common goal. The sum total of a leader’s roles, tasks and responsibilities and interpersonal influences constitutes leadership in his opinion.
As more Millennials assume leadership positions around the world, organizations are becoming increasingly concerned with how to ensure their success. However, most existing research on those born between the early ‘80s and late ‘90s is skewed toward understanding what a narrow, typically Western, population wants. Conclusions based on such a limited sample could lead to bad decisions (and missed opportunities) around attracting, retaining, and developing millennial leaders in a global business environment.
Most workplaces face constant imperatives for change - from trivial-seeming matters such as installing new office printers to major ones such as implementing new policies to support diversity. The question of how to drive change, though, is perennially vexing.
Our own brains regularly deceive us in order to make sense of the world we live in. Most of the time, it’s nothing more than an innocent effort to save face. Our brain will tell us we’re smarter and better looking than everyone else, and that any fault brought to our attention should probably be blamed on someone else. It will advocate for our convictions, pointing out any evidence that supports them and politely ignoring any that doesn’t. And it will even spare us from the mental strain of thinking beyond the stereotypes it has so conveniently crafted for us. The human brain is our best friend, and our worst enemy, and unless we keep one eye peeled, it can hijack our learning completely.
