Inclusive bias

Selection bias is the bias introduced by the selection of individuals, groups or data for analysis in such a way that proper randomization is not achieved, thereby ensuring that the sample obtained is not representative of the population intended to be analyzed. The phrase "selection bias" most often refers to the distortion of a statistical analysis, resulting from the method of collecting samples.

If the selection bias is not taken into account, then some conclusions of the study may be false. Sampling bias is systematic error due to a non- random sample of a population, [2] causing some members of the population to be less likely to be included than others, resulting in a biased sampledefined as a statistical sample of a population or non-human factors in which all participants are not equally balanced or objectively represented.

A distinction of sampling bias albeit not a universally accepted one is that it undermines the external validity of a test the ability of its results to be generalized to the rest of the populationwhile selection bias mainly addresses internal validity for differences or similarities found in the sample at hand. In this sense, errors occurring in the process of gathering the sample or cohort cause sampling bias, while errors in any process thereafter cause selection bias.

It is closely related to the survivorship biaswhere only the subjects that "survived" a process are included in the analysis or the failure biaswhere only the subjects that "failed" a process are included.

It includes dropoutnonresponse lower response ratewithdrawal and protocol deviators. For example, in a test of a dieting program, the researcher may simply reject everyone who drops out of the trial, but most of those who drop out are those for whom it was not working. Different loss of subjects in intervention and comparison group may change the characteristics of these groups and outcomes irrespective of the studied intervention.

Philosopher Nick Bostrom has argued that data are filtered not only by study design and measurement, but by the necessary precondition that there has to be someone doing a study. In situations where the existence of the observer or the study is correlated with the data, observation selection effects occur, and anthropic reasoning is required. An example is the past impact event record of Earth: if large impacts cause mass extinctions and ecological disruptions precluding the evolution of intelligent observers for long periods, no one will observe any evidence of large impacts in the recent past since they would have prevented intelligent observers from evolving.

Hence there is a potential bias in the impact record of Earth. In the general case, selection biases cannot be overcome with statistical analysis of existing data alone, though Heckman correction may be used in special cases. An assessment of the degree of selection bias can be made by examining correlations between exogenous background variables and a treatment indicator. However, in regression models, it is correlation between unobserved determinants of the outcome and unobserved determinants of selection into the sample which bias estimates, and this correlation between unobservables cannot be directly assessed by the observed determinants of treatment.

Much has been written about the importance of various aspects of the conduct of a SR: how to best search computerized databases; whether or not reviewers should be masked to the authors and journals and outcomes of studies being reviewed; how to assess studies for the risk of bias; and the strengths and weaknesses of various different methods of statistically combining the results.

For example, in a recent Comparative Effectiveness Review on drugs to treat low bone density, the EPC identified nine prior meta-analyses evaluating the antifracture efficacy of alendronate compared with placebo or no treatment. One might expect that all the trials included in earlier meta-analyses would be included in later meta-analyses, but this is not the case.

One meta-analysis published in included 10 trials, while another published in included only 5: 4 were among the 10 trials in the meta-analyses, but 1 trial published in was not.

Some of the differences in trial inclusion could be explained by whether data were included on vertebral and nonvertebral fractures; whether nonvertebral fractures were treated as a general group; whether nonvertebral fractures were split out into fractures of the hip or wrist; or whether patient populations were considered as secondary prevention or as primary prevention.

These differences in which trials were included led to differences in conclusions.

In one meta-analysis, 3 the conclusion was that the decrease in nonvertebral fractures was not statistically significant. In another meta-analysis 4 published 3 years earlier, the conclusion was that the beneficial effect of alendronate compared with placebo on nonvertebral fractures was statistically significant.

All EPCs can tell similar stories. Conflicting conclusions confuse decisionmakers, especially if all reviews purported to answer the same question and the differences in the applicability of the evidence are not clearly denoted. Bias results from systematic alteration from the truth.

The Key to Inclusive Leadership

Although we do not know the exact truth, different conclusions lead readers to believe that alternate inclusion and exclusion criteria result in biased conclusions. In order to investigate the potential for this source of bias and identify methods studies that investigate how best to reduce it, we searched for studies that examined two or more SRs of the same topic, evaluating the impact of variation in study inclusion.

We found a very small number of relevant studies Table 1. Search terms were specified a priori, and the groups were instructed to find and include all study designs, including non-English language, case series, ecological, cross-sectional, case-control, cohort, and intervention studies. Both review groups agreed on including articles, but disagreed on 72 articles Center A included 52 papers not included by Center B, and Center B included 20 papers not included by Center A.

Sixty-three of the 72 discrepancies occurred in screening title and abstract; 9 of the 72 discrepancies occurred during review of full-text articles. Other similar retrospective studies also found differences in their lists of included studies and sometimes different conclusions Table 1.

Although the amount of evidence is small to confirm the presence of bias, the potential for bias is possibly quite large.

Studies evaluating reasons for discrepancies in included studies among systematic reviews. Other authors have addressed reasons for discrepant results from meta-analyses on the seemingly same topics. He gives examples of situations where inclusion criteria for meta-analyses were apparently specified in way that would obtain results that supported the viewpoints of the authors rather than reflecting questions of clinical uncertainty. Guidance is intended to reduce inconsistencies and risk of bias.

Unfortunately, because there are no available studies to guide us how best to reduce this variation, what follows is based on fundamental principles of SRs and the experience of the EPC program. Inconsistencies and bias can certainly occur during the development of key questions, which define the scope of the review and details the population sintervention scomparator soutcome stiming, and setting PICOTSand sometimes even the study designs or study characteristics of interest.

The methods used by the EPC program at this earlier stage are discussed elsewhere.What makes people feel included in organizations? Feel that they are treated fairly and respectfully, are valued and belong? But mostly it comes down to leaders. And this really matters because the more people feel included, the more they speak up, go the extra mile, and collaborate — all of which ultimately lifts organizational performance.

Given this formula, inclusive leadership is emerging as a unique and critical capability helping organizations adapt to diverse customers, markets, ideas and talent. Our previous research found that inclusive leaders share a cluster of six signature traits:.

The answer depends on who is asking. But this is not all. Raters are not looking for a simple acknowledgment of bias, tinged with a fatalistic sense that little can be done about it. They care about awareness of bias coupled with two additional behaviors:. Why are humility and empathy so important in this context? Humility encourages others to share their feedback e. Empathy and perspective taking gives people hope that a leader cares about them and takes their views into account, rather than barreling on with preconceptions or a narrow set of ideas about their perspectives.

Moreover, it creates a sense of personal connection between leaders and a diverse set of stakeholders, making it easier to make and implement shared decisions. How can leaders put these insights into practice? One tactic is to establish a diverse personal advisory board PAD — a group of people, often peers, who have regular contact with the leader and whom the leader trusts to talk straight. These trusted advisers can give leaders granular feedback on everyday interpersonal behaviors that support or inhibit inclusion, for example: Does the leader give equal time to all meeting participants, or favor those who are co-located over those who have dialed in?

Does the leader always refer to one gender when giving examples or both? Does the leader use a broad spectrum of imagery when addressing a diverse audience, or imagery such as sport metaphors or all male iconography that represents only one group of people?

Because a PAD is ongoing, leaders can receive feedback on whether the changes they make are hitting the mark. A second tactic is for leaders to share their learning journey about recognizing and addressing biases. These actions express humility, help leaders to test and build on their insights and role model the importance of humility in addressing biases. A third tactic is for leaders to immerse themselves in uncomfortable or new situations which expose them to diverse stakeholders, for example by attending an Employee Resource Group meeting, or sitting in different parts of the workplace each week.

Exposure, combined with open-ended questions, helps to expand horizons and disrupt pre-conceived ideas. Inclusive leadership is a critical capability to leverage diverse thinking in a workforce with increasingly diverse markets, customers, and talent.

We have previously observed that only one in three leaders holds an accurate view about their inclusive leadership capabilities. A third believe they are more inclusive than they are actually perceived by those around them to be, while a third lack confidence in their inclusive leadership capability and so do less than they could to actively guide others and challenge the status quo.

Selection bias

Becoming more aware is critical to self-development, but awareness in isolation is not sufficient. This requires effort, but fortunately the circle of learning is virtuous.By Chris Weller.

We know from science that leaders can solve for bias all day long, but still fail to create an inclusive culture. Take a hypothetical manager, Bob. He takes every step he can to avoid making a biased decision: asking others, gathering data, checking his thinking.

The problem here is that Bob mitigated his biases, but failed to explain his decision-making. Thus, they could feel excluded even though Bob acted without bias. And yet, organizations reportedly spend billions on diversity training, often in the hopes their employees will start including more. We can think of biases as mental shortcuts our brains make when prompted with a choice. For example, a safety bias causes us to make decisions that avoid harm or loss.

The upside is we may avoid negative outcomes. But we may also overcorrect and miss out on risky but lucrative ones. Inclusion, on the other hand, is the sense we belong and can meaningfully contribute to the group.

Only when leaders focus on both can they feel truly confident that their teams are arriving at the most innovative decisions with the right people involved.

Inclusive Leadership and Unconscious Bias

We have designed a simple Inclusive Leadership Feedback Process which combines self-assessment with feedback on leadership behaviours, and this often forms part of our coaching offering. For more information on leadership coaching, please visit our sister site Rachael Ross Coaching. In global organisations, managing across cross-cultural boundaries can really get in the way of effective collaboration, not least when a new joint venture is being launched or a company is expanding into a new country.

We have developed a series of cross cultural self-assessment tools and often explore this theme as part of our leadership workshops. Unconscious Bias is another key theme in our leadership programmes. Exploring the latest thinking on the neuroscience and psychology behind our thinking is fascinating for delegates. We go on to surface the bias that gets in the way of balanced decision making and challenge delegates as they make plans to change their behaviour as leaders. We develop short workshops on this, or include it in longer leadership programmes, often combind with coaching to deepen the learning.

Just last year McKinsey and Company released research showing that companies that are gender-diverse are 15 percent more likely to outperform financial expectations. Meanwhile, ethnically diverse companies can enjoy a 35 percent likelihood to outperform expectations. Perception is not reality however. An MIT economist published a study that found an interesting dissonance between actual and perceived diversity when it comes to two important metrics: employee satisfaction and financial performance.

Offices that presented the perception of a diverse work environment yielded an increase in satisfaction among employees, however, perceived diversity did not lead to improved revenues. Conversely, the actual presence of diversity reduced satisfaction, but drove financial results higher.

Why is this the case? The answer may be in our subconscious; our most primal instincts that steer us to avoid risk and stay in our comfort zone. More researchers and HR pros are giving credence to the concept of unconscious biases playing a significant role in workplace diversity.

Unconscious bias also referred to as implicit bias affects how we feel about everything from gender, race, age, weight and religion -- all of which are driving factors underlying homogenous workforces -- even in companies that claim to foster diversity.

While unconscious bias is not an entirely new notion, it is just starting to gain momentum in corporate efforts to advance workplace diversity. Many organizations are even developing specific departments or programs to combat the impact of unconscious biases -- often referred to as diversity and inclusion. This is a telling shift as it indicates the business world is finally admitting to an issue that has silently segmented workplaces for ages.

Our brains are bombarded with about 11 million bits of information every second, yet we are only equipped to consciously process about 40 bits. So where does all of the unconsciously processed information go?

Here’s Why Bias and Inclusion Are Fundamentally Different

This information becomes deeply engrained in the thoughts, feelings and beliefs we carry with us. These subconsciously absorbed slices of information are stored, and convert into deep-seated biases that inform every snap judgment we make, whether good or bad, and whether we like it or not.

Unconscious biases manifest as survival mechanisms, helping us to better sift through the constant barrage of information, to make decisions based on instinct rather than logic. One common manifestation of this information is micro-aggression; subtle slices of aggressive behavior body language, phrasing, etc.

Individuals may not intend to release any sort of aggressive negativity -- but it happens and it impacts everyone in the vicinity.Taking a practical, not political approach, SkillPath embraces proactive training based on positive psychology—research-based and designed for the real world, with practical solutions for all levels of your organization.
