A snowball effect[1] is a process that starts from an initial state of small significance and builds upon itself (an exacerbating feedback), becoming larger (graver, more serious), and also perhaps potentially more dangerous or disastrous (a vicious circle), though it might be beneficial instead (a virtuous circle). This is a cliché in cartoons and modern theatrics, and it is also used in psychology.
The common analogy is with the rolling of a snowball down a snow-covered hillside. As it rolls the ball will pick up more snow, gaining more mass and surface area, and picking up even more snow and momentum as it rolls along.
In aerospace engineering, it is used to describe the multiplication effect in an original weight saving. A reduction in the weight of the fuselage will require less lift, meaning the wings can be smaller. Hence less thrust is required and therefore smaller engines, resulting in a greater weight saving than the original reduction. This iteration can be repeated several times, although the decrease in weight gives diminishing returns.
The startup process of a feedback electronic oscillator, when power to the circuit is switched on, is a technical application of the snowball effect. Electronic noise is amplified by the oscillator circuit and returned to its input filtered to contain primarily the selected (desired) frequency, gradually getting stronger in each cycle, until a steady-state oscillation is established, when the circuit parameters satisfy the Barkhausen stability criterion.
A three-wave longitudinal study conducted with preadolescent boys and girls (N = 231 at Time 1 [T1]) was used to assess the hypotheses that aspects of social withdrawal would be predictors of a "snowball" cascade of depressed affect, and that friendship experiences would moderate these effects. Consistent with these hypotheses, multilevel modeling showed that measures of avoidance and exclusion at T1 were associated with concurrent levels of depressed affect and were antecedent to escalating trajectories of depressed affect over time. These accelerating growth curves fit a snowball cascade model. The analyses also showed the protective effects of friendship. Specifically, the snowball effect was limited to avoidant and excluded children who were friendless. Depressed affect did not increase among avoidant and excluded children who were friended.
In total, 1 in 1000 individuals carries a germline mutation in the PKD1 or PKD2 gene, which leads to autosomal dominant polycystic kidney disease (ADPKD). Cysts can form early in life and progressively increase in number and size during adulthood. Extensive research has led to the presumption that somatic inactivation of the remaining allele initiates the formation of cysts, and the progression is further accelerated by renal injury. However, this hypothesis is primarily on the basis of animal studies, in which the gene is inactivated simultaneously in large percentages of kidney cells. To mimic human ADPKD in mice more precisely, we reduced the percentage of Pkd1-deficient kidney cells to 8%. Notably, no pathologic changes occurred for 6 months after Pkd1 deletion, and additional renal injury increased the likelihood of cyst formation but never triggered rapid PKD. In mildly affected mice, cysts were not randomly distributed throughout the kidney but formed in clusters, which could be explained by increased PKD-related signaling in not only cystic epithelial cells but also, healthy-appearing tubules near cysts. In the majority of mice, these changes preceded a rapid and massive onset of severe PKD that was remarkably similar to human ADPKD. Our data suggest that initial cysts are the principal trigger for a snowball effect driving the formation of new cysts, leading to the progression of severe PKD. In addition, this approach is a suitable model for mimicking human ADPKD and can be used for preclinical testing.
The snowball compounds during its travel down the hill. The bigger it gets, the more snow it packs on with each revolution. The snowball effect explains how small actions carried out over time can lead to big results.
You can harness the power of the snowball effect by investing in the same type of businesses that have made Warren Buffett so wealthy over time. Specifically, companies with strong and durable competitive advantages and shareholder friendly managements, trading at fair or better prices.
Like the classic cartoon image of a small snowball rolling down a mountain, picking up more snow along the way, and eventually becoming a monstrous juggernaut by the time it reaches the bottom, small errors by Medicare Advantage Organization claim evaluators can add up to thousands of patients being denied necessary care and millions of dollars in lost reimbursement for providers.
Researchers often include demographic variables as control variables to make the estimation of the main effects more accurate. For instance, Im, et al. [22] found that the user age and income negatively and positively correlate with the consumer adoption of new products, respectively. Martin, et al. [23] found that age and education are covariates with the user adoption of telecommunication innovation. Other studies have shown that gender makes a difference in the user attitude toward computers, wherein men are less anxious about computers than women [24]. For more accurate estimates of main relationships, therefore, this study control for the effects of demographic variables, including education, gender, age, and income, on both outcomes of behavioral intention and actual participation.
Among the control variables, age had a positive effect on behavioral intention, and gender (male = 1, female = 0) had a negative effect on actual participation, whereas education and income did not make too much a difference in either. The results also suggest that the user behavior in online environmental communities is somewhat distinct from the typical IS user behavior, in which age and gender exhibit opposite effects, whereas education and income make differences.
How often do you find yourself standing on the side of a snow-capped mountain, frozen to the spot while helplessly looking up at the rapidly growing and descending snowball of your IT nightmares? Metaphorically-speaking of course, but hopefully you get the point.
These results shed new light on the recent debate on wealth taxation. In the presence of heterogeneous returns, a wealth tax could be more efficient than a capital income tax. Using wealth instead of capital income as a tax base would reduce the burden on high-return investments and may motivate taxpayers to direct their savings toward more productive investment. This could benefit society via positive effects on employment and firm creation. Incidentally, the introduction of a wealth tax would also provide more precise data on wealth, which could help explain the dynamics of inequality, its roots, and its relationship with other economic phenomena.
In contrast, the "avalanche method" focuses on paying the loan with the highest interest rate loans first. Similar to the "snowball method," when the higher-interest debt is paid off, you put that money toward the account with the next highest interest rate and so on, until you are done. By focusing on the loans that are the most expensive to carry in the long run, you should pay less over time as the higher interest loans are addressed first.
You may save some money with the "avalanche method," but if the principal is large, the time it may take to pay off debt with the highest interest can be discouraging and make it difficult to stick to the plan. Paying off small debts quickly can feel rewarding. If you prefer to see progress quickly and work your way up, then the "snowball method" may be a better fit for your debt management goals.
So.. why are so many people of the impression that hitting certain milestones will mean that some form of snowball effect will take place? Like after they hit 100, suddenly hitting 1,000 becomes much easier, that growth just suddenly happens? I don't understand. I've never thought that and am genuinely curious of the logic behind it.
I went on to capture the next 3 months: As you can see, with the exception of a spike to almost 100 on one day in September, I actually averaged less than 50 per day, but still ended up with approximately 2,400 subscribers. No increase in subscribers. No snowball effect after hitting 1,000 subscribers. No difference in "tier."
Here you'll see June through December 2018: This is when I was at 90,000 subscribers all the way through 130,000 subscribers. Again, I saw no "snowball effect" or "tiered" change in how many subscribers I obtained from my videos. I averaged approximately 150-250 subscribers per day for a long time.
Overcoming organizational culture to create lasting change may seem daunting. Remember, the diversity snowball effect is a process that will require an ongoing, intentional commitment to achieve a long-term goal. The PRESS model is just one tool that can be used to facilitate this process.
Role-playing scenarios can enhance investment and participation. Always consider psychological safety when asking participants to engage in any role-playing activity to avoid potential adverse effects. We highly recommend a discussion for each group to agree on ground rules of respectful learning prior to engaging in any role-playing scenarios (embrace ambiguity, commit to learning together, listen actively, create a brave space, suspend judgment, etc.). It is reasonable to review these ground rules prior to each role-playing discussion.
Possible questions and an answer key are provided below. These can be useful to document effectiveness in learning and knowledge gained but can also be useful to help learners identify that they may not actually know everything about a DEI topic, even if they have participated in presentations on it previously.
