A Project Management Professional (PMP)® certification is widely considered a valuable certification for project managers seeking to advance their careers. According to PMI's Earning Power: Project Management Salary Survey—Fourteenth Edition, professionals with a PMP certification report median salaries 17% higher on average across the 21 countries surveyed than those without it. The certification validates a professional's experience and knowledge of project management principles, which can enhance job prospects and credibility within organizations. #### What are the best certifications for project managers? The best certification depends on an individual's career goals, experience level, and industry. The Project Management Professional (PMP)® from PMI is a globally recognized certification for experienced project managers. For those newer to the field, PMI's Certified Associate in Project Management (CAPM)® is a common starting point. Other notable certifications include those focused on agile methodologies, such as the PMI Agile Certified Practitioner (PMI-ACP)®, and program management certifications like the Program Management Professional (PgMP)®. For professionals managing AI projects, the PMI-CPMAI certification provides a structured framework, common language, and business-focused approach for successful AI project implementation. #### How does PMI support career growth for professionals? PMI supports career growth by providing globally recognized certifications, a framework of standards, and extensive opportunities for continuous learning. Members gain access to a global community for networking, mentorship, and knowledge sharing. The organization also produces research and thought leadership on emerging trends, helping professionals stay current with skills in areas like AI, agile practices, and strategic business management. These resources are designed to help professionals at all levels enhance their skills and advance their careers. #### What is the PMBOK® Guide? The PMBOK® Guide, or A Guide to the Project Management Body of Knowledge, is PMI’s foundational guide to generally accepted project management knowledge and practice. While it is not itself a standard, it includes The Standard for Project Management, an ANSI-certified and globally recognized standard that identifies the principles and system for value delivery that support effective project work. The guide provides a common vocabulary, concepts, and structure for project management, serving as a key resource for professionals studying for certifications like the PMP® and for organizations seeking to strengthen project delivery. #### How is AI changing project management? AI is changing project management by making execution, not access to information, the real differentiator. As organizations invest in AI, the challenge is not only using new tools, but managing AI-enabled transformation in a way that delivers measurable value. Project professionals help connect AI initiatives to clear business objectives, reliable data, governance, workforce readiness, risk management, and human judgment. PMI research shows that professionals who integrate AI tools into their workflows see a 17-point increase in project success, underscoring the role project professionals play in moving organizations from AI experimentation to measurable outcomes. #### What are the most important skills for a project manager? Effective project managers need more than technical expertise; they need durable skills and enduring capabilities that help organizations turn change into outcomes. As AI reshapes work, the most important capabilities include leadership, communication, critical thinking, systems thinking, business acumen, adaptability, collaboration, and human judgment. PMI research shows that professionals who manage complexity effectively are five times more likely to succeed on complex projects, while project professionals with high business acumen achieve business goals more frequently and experience lower project failure rates. #### How can I get involved with the PMI community? Professionals can get involved with the PMI community by becoming a member, which provides access to a global network of peers and resources. Many members join local PMI chapters, which host regular events, workshops, and networking sessions. Online, PMI's projectmanagement.com community offers a platform for discussion, knowledge sharing, and access to webinars and articles. Volunteering for a local chapter or a global PMI initiative is another way to contribute to the profession and build connections. #### What is the difference between PMP and CAPM? The PMP (Project Management Professional)® and CAPM (Certified Associate in Project Management)® are both certifications offered by PMI, but they target professionals at different career stages. The CAPM is an entry-level certification designed for individuals with little or no project experience, validating their understanding of fundamental project management knowledge and terminology. The PMP is for experienced project managers and requires a combination of formal education and years of documented project leadership experience, making it a more advanced and globally recognized certification. #### How does PMI support social impact? PMI supports social impact by helping individuals, nonprofits, NGOs, and communities use project management to turn purpose into measurable outcomes. Through the PMI Educational Foundation, PMI expands access to project management education for youth worldwide, including underserved and underrepresented populations. Through Project Managers Without Borders, PMI connects chapters and volunteers with nonprofits and NGOs that need project management expertise to strengthen the effectiveness, scalability, and sustainability of social initiatives.

In the 19th century, biologists held that a woman’s brain was too small for intellect but large enough for household chores. When the tiny-brain theory bit the dust (elephants, after all, have bigger brains than men), scientists began a long, fruitless attempt to locate the biological basis of male superiority in various brain lobes and chromosomes. By the 1960s sociobiologists were asserting that natural selection, operating throughout the long human prehistory of hunting and gathering, had predisposed males to leadership and exploration and females to crouching around the campfire with the kids. Recent studies suggest there may be some real differences after all. And why not? We have different hormones and body parts; it would be odd if our brains were 100% unisex. The question, as ever: What do these differences augur for our social roles, in particular the division of power and opportunity between the sexes? Don’t look to the Flintstones for an answer. However human beings whiled away their first 100,000 years or so, few of us today make a living tracking down mammoths or digging up tasty roots. Much of our genetic legacy of sex differences has already been rendered moot by that uniquely human invention: technology. Military prowess no longer depends on superior musculature or those bursts of hormones that prime the body for combat at ax range. As for exploration, women — with their lower body weight and oxygen consumption — may be the more “natural” astronauts. But suppose the feminists’ worst-case scenario turns out to be true, and males really are better, on average, at certain mathematical tasks. If this tempts you to shunt all the girls back to home ec, you probably need remedial work in the statistics of “averages” yourself. Just as some women are taller and stronger than some men, some are swifter at abstract algebra. Many of the pioneers in the field of X-ray crystallography — which involves three- dimensional visualization and heavy doses of math — were female, including biophysicist Rosalind Franklin, whose work was indispensable to the discovery of the double-helical structure of DNA. Then there is the problem that haunts all studies of “innate” sex differences: the possibility that the observed differences are really the result of lingering cultural factors. Girls’ academic achievement, for example, as well as apparent aptitude and self-esteem, usually takes a nose dive at puberty. Unless nature has selected for smart girls and dumb women, something is going very wrong at about the middle-school level. Part of the problem may be that males, having been the dominant sex for a few millenniums, still tend to prefer females who make them feel stronger and smarter. Any girl who is bright enough to solve a quadratic equation is smart enough to bat her eyelashes and pretend that she can’t. Teachers too may play a larger role than nature in differentiating between the sexes. Studies show they tend to favor boys by calling on them more often and pushing them harder. Myra and David Sadker, professors of education at American University, have found that girls do better when teachers are sensitized to gender bias and refrain from sexist language, such as the use of ) “man” to mean all of us. Single-sex classes in math and science can also boost female performance by eliminating favoritism and male disapproval of female achievement. The success of such simple educational reforms only underscores the basic social issue: Given that there may be real innate mental differences between the sexes, what are we going to do about them? A female advantage in reading emotions could be interpreted to mean that males should be barred from psychiatry — or that they need more coaching. A male advantage in math could be used to confine girls to essays and sonnets — or the decision could be made to compensate by putting more effort into girls’ math education. In effect, we already compensate for boys’ apparent handicap in verbal skills by making reading the centerpiece of grade-school education. We are cultural animals, and these are ultimately cultural decisions. In fact, the whole discussion of innate sexual differences is itself heavily shaped by cultural factors. Why, for example, is the study of innate differences such a sexy, well-funded topic right now, which happens to be a time of organized feminist challenge to the ancient sexual division of power? Why do the media tend to get excited when scientists find an area of difference and ignore the many reputable studies that come up with no differences at all? However science eventually defines it, la difference can be amplified or minimized by human cultural arrangements: the choice is up to us, and not our genes. ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/archive/6719421/making-sense-of-la-difference/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/archive/6719421/making-sense-of-la-difference/"},"headline":"Making Sense of la Difference","datePublished":"1992-01-20T05:00:00.000Z","dateModified":"2026-02-27T22:15:04.951Z","description":"Few areas of science are as littered with intellectual rubbish as the study of innate mental differences between the sexes.
